You can be atheist agnostic - you don’t actively participate in religion or worship but believe it is fundamentally unknowable if there is or is not a god, you can also be theistic agnostic (though this is rare in the modern lexicon) which would be where you do participate in religion (or religious practices) but still believe it to be unanswerable. To be gnostic is to believe it is knowable (and perhaps that one does know), it too can be either theist or atheist in nature.

Atheist is literally “not theist” which would include nothing, none, agnostic (the belief that it’s impossible to determine the existence or absence of, in this context, God). It could even be argued that people who believe in God but do not participate in theistic practices (eg lapsed Catholics) are atheists. It does not require or even imply some position against religion.

It’s nice to be able to open up an old computer to add more RAM/Storage/etc., but also get that making everything integrated and soldered improves durability and reliability.

If you’re willing to believe that soldering in a hard drive has anything at all to do with reliability I don’t even know what to tell you. The fact they apple will, with a straight face, charge $300+ to upgrade from 256gb of ssd capacity to 512gb should also be a clue…you can get 1tb for that price. and that price gauging on selling the customer parts at over 100% markup is the sole reason they solder them in.
