Unless the off-exchange plan has some specific benefit to you, I personally would switch over to the exchange version of the plan this fall. If your income disqualifies you for subsidies, that's not a problem.
You could also simply decline the subsidies when you sign up, and if your income and the subsidy situation changes during 2023, claim them at tax time via Form 8962.
(If you're on a Silver plan and in CSR range, then it may make sense to try to get those when you sign up; those are not retroactive and not reconciled at tax time.)
