Here's the second option I mentioned earlier. It scans through all scenes in the scene manager and removes the affecting fragments. The lookup table acts as a hierarchy. If the parent fragment is found, it tries to remove the child fragments as well.

local SceneWhitelist={
    crownCrateKeyboard=true;
    crownCrateGamepad=true;
};
 
local Fragments={
    [FRAME_PLAYER_FRAGMENT]={-- Calls SetFrameLocalPlayerInGameCamera()
--      Calls SetFrameLocalPlayerTarget()
        [FRAME_TARGET_STANDARD_RIGHT_PANEL_FRAGMENT]                =true;
        [FRAME_TARGET_STANDARD_RIGHT_PANEL_MEDIUM_LEFT_PANEL_FRAGMENT]      =true;
        [FRAME_TARGET_FURNITURE_BROWSER_FRAGMENT]               =true;
        [FRAME_TARGET_CRAFTING_FRAGMENT]                    =true;
        [FRAME_TARGET_CRAFTING_GAMEPAD_FRAGMENT]                =true;
        [FRAME_TARGET_CENTERED_FRAGMENT]                    =true;
        [FRAME_TARGET_OPTIONS_FRAGMENT]                     =true;
        [FRAME_TARGET_STORE_WINDOW_FRAGMENT]                    =true;
        [FRAME_TARGET_GAMEPAD_FRAGMENT]                     =true;
        [FRAME_TARGET_GAMEPAD_OPTIONS_FRAGMENT]                 =true;
        [FRAME_TARGET_LEFT_GAMEPAD_FRAGMENT]                    =true;
        [FRAME_TARGET_TRADING_HOUSE_GAMEPAD_FRAGMENT]               =true;
        [FRAME_TARGET_GAMEPAD_RIGHT_FRAGMENT]                   =true;
 
--      Calls SetFullscreenEffect()
        [FRAME_TARGET_BLUR_STANDARD_RIGHT_PANEL_FRAGMENT]           =true;
        [FRAME_TARGET_BLUR_STANDARD_RIGHT_PANEL_MEDIUM_LEFT_PANEL_FRAGMENT] =true;
        [FRAME_TARGET_BLUR_CENTERED_FRAGMENT]                   =true;
        [FRAME_TARGET_BLUR_STORE_WINDOW_FRAGMENT]               =true;
        [FRAME_TARGET_BLUR_GAMEPAD_FRAGMENT]                    =true;
        [FRAME_TARGET_LEFT_BLUR_GAMEPAD_FRAGMENT]               =true;
        [FRAME_TARGET_TRADING_HOUSE_BLUR_GAMEPAD_FRAGMENT]          =true;
        [FRAME_TARGET_BLUR_GAMEPAD_RIGHT_FRAGMENT]              =true;
        [FRAME_TARGET_BLUR_FULLSCREEN_FRAGMENT]                 =true;
 
--      Calls SetFrameLocalPlayerLookAtDistanceFactor()
        [FRAME_TARGET_DISTANCE_GAMEPAD_FAR_FRAGMENT]                =true;
    };
};
--Fragments[FRAME_PLAYER_ON_SCENE_HIDDEN_FRAGMENT]=Fragments[FRAME_PLAYER_FRAGMENT];--  Alias for FRAME_PLAYER_FRAGMENT (Only used for item previews, not actually registered to any scenes)
 
local ProcessScene; do--    function ProcessScene(scene)
    local Lookup=Fragments;
    function ProcessScene(scene)
        local lookup=Lookup or Fragments;-- Save a copy, it changes with recursion
        local list=scene.fragments;--   Scene fragment list
 
        local i=#list;--    For doesn't handle changes in index mid-loop
        while i>0 do
            local val=lookup[list[i]]; i=i-1;
            if val then
                table.remove(list,i+1);--   We decremented the index already
                if type(val)=="table" then
                    Lookup=val;--   Select lookup table
                    ProcessScene(scene);--  Recursive iteration
                    Lookup=lookup;--    Restore lookup table
 
                    i=math.min(i,#list);--  Make sure we're still within list boundries
                end
            end
        end
    end
end
 
for name,scene in pairs(SCENE_MANAGER.scenes) do
    if not SceneWhitelist[name] then ProcessScene(scene); end
end

This is also experimental and may affect different parts of the UI. One noted issue so far is item previews are disabled in the Collections and Crown Store UIs. SetFrameLocalPlayerInGameCamera() is required for GetPreviewModeEnabled() to return true.
