Shop Pay and Third-Party Payment Processor

I’m finding conflicting information whether Shop Pay is allowed to be enabled/used when utilizing a third-party payment processor. I know the difference between Shop Pay and Shopify Payments, my question is whether Shop Pay can be used without Shopify Payments. and find some sources say Shop Pay can only be enabled if you are using Shopify Payments, others say it can be used along with any third-party payment processor.

You can use shop pay without shopify payment as most store owner dont know about shopify payment and they have their shop pay active. i hope this helps
