Reclaim apple intelligence disk space

I have a MacMini Intel 2018 with a 256 GB internal disk and a 2 TB external drive. Because the small internal drive, I already moved to the external drive everything that could be moved, but still I can only keep arount 20 GB of free space.

Today I read that latest version of MacOS (Sequioa 15.3) will enable Apple Intelligence by default, which will take 7 GB out of my already small available disk space. Since I don't care about Apple Intelligence, I wonder what would happend if I disable it on Settings:

a) The space taken will be freed ?

b) If not freed automatically, is there a way to manually reclaim that space ?

TIA

Victor
