Unfortunately that's not supported - the customer can edit their email in case of errors or they want to use another one etc.

You can achieve this by creating Checkout sessions explicitly for known customers by providing the customer parameter:
https://stripe.com/docs/api/checkout/sessions/create#create_checkout_session-customer

But this is not possible with Payment Links -- you need to create a Checkout session for each payment (including creating the customer if you don't already have one)
