Alt + Tab experience can now be turned off from the browser using this newly added flag
This flag that was just added today to Edge Version 89.0.736.0 (Official build) canary (64-bit) edge://flags/#edge-window-tab-manager can disable Alt + Tab experience the description says: "Allows Windows to show open Microsoft Edge tabs in OS experiences like Alt + Tab, pinned sites, and more. – Windows" so regardless of what your settings are in Windows you can stop Edge tabs to appear as separate windows in Alt + Tab view.
