Is your feature request related to a problem? Please describe.
Attestation deployables includes signatures/checksums that may not necessarily be required.

Describe the solution you'd like
Add a list of exclusions. Each exclusion is a regex applied to the target artifact filename (full path)

Describe alternatives you've considered
No current option to skip certain deployables such as signatures/checksums.

Additional context
Github attestation has a (current) limit of 2500 files. There's no need to attest signatures/checksums for example.
