Hello .. if you are asking ‘can’ as ‘can it be done’ then the answer is yes.
If you are asking that ACF Extended ‘include’ Stripe payment processing then, while I can not speak for the developer of this plugin, that probably adds another whole layer of development and potential support (time and effort) on top of this plugin.
I was working on adding a form that integrated with (used) Stripe payments. I have been side tracked for months with other things life has thrown at us but did have it kind of working. It was to allow ‘donations’ to a charity and options for selecting a fixed amount or entering your own amount. I got it to process and do the calculations but some of the hidden stuff calls and ‘json’ stuff I still need to make cleaner. Since then he has made/fixed/added features that may make that easier or require us to change our code a little but as I said in first line it no doubt can be done..
I hope to get working on it again mid Jan after the holidays are over.
