bootc install: `--block-setup tpm2-luks` doesn't work if you have a install toml file

So I wans trying to use my favorite thing today: `bootc install to-disk --wipe --block-setup tpm2-luks`

It no longer works from centos or derivatives. I tried adding a config with `block = ["tpm2-luks"] but' it's not getting picked up. Fedora still work with tpm2-luks because it has no install config. I am able to install with luks if I delete 20-rhel.toml from /usr/lib/bootc/install
