You're not VAC banned. You have a game ban, which can be caused by other violations, not just cheating.

1 game ban on record | Info
5 day(s) since last ban
you have a gameban and not a vacban. now seeing you played CS2, PUBG and dota 2 in the last 2 weeks, then i can safely say, gameban can be given for one of a few things and its permanent. FYI this is a community only forum and not an appeal forum

How can I get rid of it?

Your Game ban has nothing to do with VAC or this forum.
