The Yakima round bar roof rack # Y00408, # Y00148, # Y03536, and # Y00245 that fits your 2021 Chevy Trailblazer with a naked roof does not require any drilling to install as it attaches via fixed mounting points on the roof.
I attached a picture that shows how the rack attaches to your roof as well.
