Do I need to enable Journaling on a Mac Pro M2 SSD? I am booting from an M2 SSD (PCI) on my Mac Pro 2012.
Running Mojave. I tried to run the Boot Camp Assistant but it doesn't run and I've seen solutions saying that you have to have Journaling enabled. If I'm using APFS, can I even enable Journaling in order to make Boot Camp work? Or if not, does that mean if you are using APFS you can't use boot camp assistant? There doesnt seem to be an option to enable Journaling on the drive so I dont want to try to force it in Terminal if its not even possible.

There’s basically zero downside for journaling the filesystem metadata and huge, huge upsides so even though you don’t need to do it, I recommend everyone does it as if they needed to. The only reason not to enable journaling is if you have some desire to test failure modes of a less robust filesystem. 

As to the larger question, the boot camp info you read likely is wrong (please link to the exact article or advice if we can help be precise if it is outdated or correct). 

What’s true is you can’t have APFS and boot camp. Pick either / or


HFS with journal and the possibility to use boot camp
APFS which journals always and no possibility to use boot camp that shares space with APFS


Now you can partition your drive to be part APFS and part HFS / bootcamp, so here is the boot camp FAQ for Mojave if you want to go ahead with that plan:
