I’m running 1x with full cable housing for the rear derailleur and hydraulic hoses, so I can’t comment on the front derailleur (I think some FD can accept full housing, but I’ve never installed one of those).
I did have to slightly drill out the removable plastic cable stop at the head tube to run full housing for the RD. I noticed the BB area had a removable contraption with a cable stop for the FD, but I didn’t pay much attention. So, I guess my comment is kinda useless, sorry :-)
