EmuDeck is already implementing replacements on Switch and is looking at other 3DS emulators. They won’t uninstall Yuzu from your Deck, but likely won’t default to using them if they’re installed. You might have to take a few extra steps with ES-DE or SRM.
I dunno about non-driver anti-cheats like EAC but Genshin Impact’s kernel-level anti-cheat has been used to aid ransomware. Driver-level anti-cheat is certainly malware, that has been settled since Sony-BMG.
