You don't need the secure boot machinery for that though, a hardware security token would do and has the advantage that you need to acknowledge actions with a tap
Tangentially, soon all those will be replaced with new hardware supporting PQ signatures.
I've started keeping important signing keys in cloud HSM products. Getting AWS KMS to sign a payload is actually very straightforward once you've got your environment variables & permissions set up properly.
