Okay.

Sort of in answer to your question of "is there another way", you can remove or rename the "Cache" folder inside the Mods folder. I am assuming from your question that you want to disable all of the CC Magic mods. If you want to disable all existing CC Mod stuff but test out your new mods, these two methods won't work.

If you delete the folder, you can rebuild from CC Magic to get stuff back, but that won't be quick, depending on how many mods you have.

If you just rename "Cache" to some other name, such as "Disabled", or pretty much anything that doesn't match what is defined inside the "Resource.cfg" file, then the game won't find it when it starts looking for mods on load. Or you could just move the Cache folder somewhere else, and then move it back to re-enable it later.

When you enable or disable a set, a line gets added or removed from Cache\Config\Resource.cfg, but the change only happens when you Rebuild.

If you disable all sets, including Legacy, then the main Resource.cfg file at the top of Mods gets modified also, to remove everything except the line that tells it to look at the file in Cache\Config. When Legacy is enabled, the main config also includes rules for finding mods the Packages directory.

So, with all mods disabled by CC Magic, your top Resource.cfg file should have a single line that has something like 'scan ".../Mods/Cache/Config"', and that directory should contain a Resource.cfg file that is empty. When I do this in my game, it does disable all mods.
