How to block docker image version of services in Github action in renovate config

Question

In my CI/CD workflow, i've added renovate but i'v some PR for version upgrade i don't want. For example, it suggest me to upgrade mysql version in my yml file defining github action workflow. Here i use :

      mysql:
        image: mysql:5.7

But it suggest me to make this upgrade

      mysql:
        image: mysql:8.0

I don't want to do it for the moment (too much work to migrate it, will do when ready)

How to deactivate in renovate this kind of suggestion ? My workflows use many services, some needs to be updated, some i don't want. I wasn't able to find which rules i need to add to my renovate file to disable upgrades proposals for only some targeted services
