How can I lock a product mirror on an RMT server

I want to lock a repo on my RMT server so all the servers using the RMT server get the same patch level as they might be patched on different dates. I can see that I can disable a product mirror but I am not sure if that will stop the servers from being able to use that mirror ?

It is possible to lock a product mirror at a point in time ? if so how can it be done ?

The way that I’ve done this is to stop the rmt-server-mirror.timer and then run “rmt-cli mirror” manually when required.
