Yes, the expected procedure would be to trust those keys for that package instead of disabling integrity checks.

This is an issue between you and your package manager and not something Mullvad or any other packager (except OpenSUSE maintainers) can fix for you.

You complain about the packaging and support of mullvad maintainers when you are having skill issues with your distro.
