OK so I learned that if you want to add a custom repository to Silverblue/Bazzite you need a special configuration .rpm file and then you just do "rpm-ostree install..." . If the repository doesn't have that special .rpm then you need to create your own .repo file inside "/etc/yum.repos.d". As for gpg keys you just copy them to "/etc/pki/rpm-gpg/" and point your .repo file to your key. - just leaving this in here for other noobs like me
