DigitalOcean Wordpress Litespeed Droplet PHP 8 Compatibility?

Hi there,
My theme (according to developers) seems to be compatible with PHP 8... I've checked DigitalOcean > Marketplace > Litespeed... it's still "old" droplet with PHP 7.4 ...
I don't really understand how to update everything myself, so maybe you can guide me in the right direction?
1. Will you be rolling out an update to support PHP 8?
2. Any guides on how to update myself to PHP 8?
