If it is concentric then I would leave well enough alone, for the time being. Use the scope for several months at least, in all seeing conditions , to get a better knowledge of how the scope performs , before fiddling with the collimation.
I used to have a 180 Skywatcher Mak and never needed to adjust it, worked fine straight out of the box, given an hour or so, time to cool to ambient temperatures.
Regret selling it now.

For me, better thing is to see images or results from this Mak when not collimated and then collimated for same target in the same night, just to make sure what i am expecting, i really don't know how good or bad even in all conditions, many liked my moon shots, and my planets aren't that bad yet but i am still not satisfied with my planetary results, but i don't that the Mak will be super for the moon and in the same night it is a junk for planets, collimation shouldn't change like this, and then again another nights the moon is still nice in results but planets are just ok or so so, but as you said, i will not tocuh collimation yet.
