Hi MORAD,
I have made an app to hide the Paypal Express (and other express checkout method like Apple Pay, Google Pay etc) on the top part of checkout page, and customer can still select Paypal method at the payment selection step.
The app is made using native Shopify functions, thus it does not affect your store existing layout or functionality at all.
The app name is Yagi Express Payment Hider (https://apps.shopify.com/yagi-express-payment-hider)
Hope this can help!
Regards,
Axel Kee
