Assigning DNS for Helix

Hello, I am looking to manually configure the DNS settings on my Helix router, but this seems to NOT be an option. This is to improve my home network security to point at Canadian Shield DNS servers. ( https://www.cira.ca/en/canadian-shield/ )

Will Videotron provide users with this ability, or will in be forced to find an ISP that allows this?

Kindest regards,
