Other payment gateway

Hi,

i want to buy this theme as u mentioned the link in plugin page:
https://preview.themeforest.net/item/travel-booking-hotel-wordpress-theme-hotel-wp/full_screen_preview/18828322?_ga=2.264119429.806003509.1622522137-1571935905.1622520907

This theme support only these 4 Payment Gateways (Offline Payment, Authorize.net, Paypal, Stripe)… Can i add another payment gateway rather than these ?

Thanks
