you can create a application or window rule via the game’s window operation menu’s “more” submenu (can use the equivilant shortcut if full screen or no border) once you open the dialog, the thing you’d be looking to add is “block compositing” set to “force”. it will automatically turn compositing back on once the process is closed
that hasn’t legally held up in the past, it’s just the yuzu devs caved in with an out of court settlement since they’d have to deal with massive legal fees anyways iirc
don’t think n64 games are even encrypted, so something like the Wii common key isn’t necessary
