Avast VPN and ublock ad tracking

Can I use both Avast VPN and Ublock ad tracking to stop trackers while keeping my VPN on? I’m currently using duckduckgo search engine. At present I’m turning it on and off which is a real pain. When using VPN the volume of tracking is unbelievable. Mainly from google. I just want to be able to use my VPN and stop the trackers.

First, I’m an Avast user and not an Avast Team member.

I can’t see a reason why the Avast VPN can’t run along side uBlock Origin Lite and uMatrix (which I use with Firefox). I rarely use a VPN, when I do I don’t disable the ad-blockers and I can’t see how they would conflict. The ad-blockers only do the work when the connection is made.
