Im using Cloudflare as my DNS should/can I disable DNS for my sites? (For speed)

Operating system: Debian 10

Ahoy! im brand spanking new to VirtualMin, but I know web dev/design.
I currently bought a VPS from OVH, their Tier 2 80gbSSD 2vcore 4GB ram varients.

I have all my DNS go through CloudFlare, So when Cloudflare sends to my websites hosted on the VirtualMin server does it then do more DNS things as its currently got all that enabled?

I know it would only be miliseconds, but I would like to remove as many barriers as possible!

So is it safe to remove/stop the DNS server on Virtualmin if I use Cloudflare as my DNS? If so, how do I do this?
