Haven't really watched Overlord s1 and s2 not really seeing the appeal to it but currently reading and watching one piece.
It's technically isekai, but it's not in your face about it. While S1 is more willing to bring it up for comic relief, and serves as an exposition tool in some cases, S2 mentions it so rarely that you can forget it's an isekai.
