If I were you I would aim for strength maintenance during the week back.
Aka, do body weight lunges, chins, push-ups while away and come back and do both the “3/3/3” and the “5/3/1” weeks back to back, e.g., Bench press 3/3/3 and then 5/3/1 right after.
you won’t get stronger but I’ve found 1/month can maintain strength nicely if complemented by other physical activity.
Not ideal but you must find a way.
your other choice is to focus on other physical areas you can improve for awhile (mobility, conditioning, endurance). I know a few guys who have been sent to the NWT/Yukon for 6-7 months and used the time to become better runners. If you are into MMA, maybe a good opportunity to run some hand/speed/footwork drills
you won’t be doing 5/3/1 but that’s what’s on the table right now. I’ve taken breaks from 5/3/1 when life demanded it, don’t worry, it’s always there for you when you get back.
