Not quite The Mandalorian comic series, although I'm guessing they might have some references like Greef Carga.
Mainly seems to follow Valance, a character introduced in the original Star Wars comics from the 70's, and who was recently added to Disney's canon, as well as the bounty hunters from the films (Boba and co.)
