Change the signature to be based on SHA256 instead of SHA1

Signed RPMs report as having bad signatures on RHEL 9 and can't be installed:
Looks like SHA1 is depreciated in RHEL 9 ( https://access.redhat.com/articles/6846411 ). Can you change the signature to be based on SHA256 instead of SHA1 ?

# rpm -i package-1-1.x86_64.rpm

Any plans to add SHA256 signatures ?
