how to disable autoupdate of workshop mods so that they dont corrupt my ongoing saves?

[strange maple]

i want them to still keep getting updates in the original steamapps/common/projectzomboid/blahblah folder but like having a separate folder with all the mods being copied to it from which the game loads the mods to itself so they dont update themselves and remain untouched

Steam does not allow disabling workshop autoupdates

It would be best to know the reason for preventing the autoupdates and then try to find a solution based on that
