disable the Sticky Header on certain page types in Woocommerce

Hi Support
Can we disable the Sticky Header on certain page types eg Product pages, Cart pages and Check Out page in WooCommerce.

As we have a problem… when you click the Wizpay – “learn more” on Product pages, the Cart page and Check Out page you can’t get to the Pop Up ‘Close’ button to close the Wizpay pop up.

NOTE: I have on to the Cart and Check Out pages and changed the “Header visibility and transparency” to be “Header is invisible and appears only when page is scrolled”
I can’t see how to do this on the Products page!
