Hello Ubansal,
1/ We’ve added the next code to show the Buy Now button https://prnt.sc/7OxdiAE7vAlT
and the next code to hide the add to cart button: https://prnt.sc/TvdZ17-mvAtm
2/ If you want to change the current functionality of the Buy now button, please post your request here https://www.8theme.com/taskboard/ If it receives enough votes from other customers, our development team will consider adding new settings in one of the upcoming updates.
3/ You need to change these settings also https://prnt.sc/cWmJz0Z9laK9 + https://prnt.sc/VGjelWLsHXHo
Kind Regards,
8theme team
