Run unity 6 game on Emulators

Hi, I’m doing a game for somebody and it was going well until they said they want to test it on android emulators. From what i know, they are not supported because they use the x86_64 architecture which is rare in real-world devices and has become deprecated. I told him to just test the game on his phone. He did but told me the game doesnt run on a broad enough selection of devices and is not satisfied. Is there a solution to this problem? I’ve been searching for 2 days and cannot find a way to compile for those emulators… Unity 6 doesnt even have a button for that x86_64 thing in the player settings:
