Payment options configuration | help needed

Dear Support,

I want to configure AED, SAR, and KWD currencies on my website.
I have 2 payment methods, Stripe and Tamara BNPL.

I need users using Stripe from anywhere in the world always to be charged only in AED despite their manual Currency selection or auto country detection.

Users from UAE, KSA and KUWAIT have an option to use/select Tamara BNPL and should be charged respectively in AED, SAR, & KWD.

Please confirm how to achieve that and if possible guide me through the setting and I will purchase the Plugin.

Look forward to hearing from you!
Thank you
