Existing Digital Ocean Server

Just getting started with Laravel and Forge, but a question has come up. I'd appreciate your thoughts.

Is it possible to use Forge with with an existing Digital Ocean Server?

Documentation has a section called "Bring Your Own Server" that I thought might apply here, but didn't want to break any links between Forge and DO.

Another post from a couple years ago a user said they didn't think this was possible at least at that time. Has has this changed much over the past couple of years?
