Option for disabling 32 bit?

[Animeshz]

It seems like 32 bit enabled pulls over another set of llvm-lib >=450MB mesa-drivers >=150MB intel-media-driver >=90MB and few minor stuffs, I would like to disable it so that since I don't usually use them often.

In current architecture of flake based setup, there doesn't seem to be a way to disable it since it is forced enable by default without customization options in flake's output.

If there's a way which is undocumented maybe, please let me know. Thanks!
