Not really. The CC validation is something GitLab have had to force
onto all new accounts due to cryptominer abuse of their free shared
CI runners :-( If you have VMs somewhere you could theoretically
spin up your own CI runners instead of using the shared runners and
that could avoid the CC validation need.

We've never used GitHub for CI with QEMU upsteam. Before this we used
Travis first, and Cirrus CI. Travis effectively killed off their free
plan for x86 builders, and Cirrus CI is too restrictive to run enough
jobs.  GitLab is our primary target
