Unity Web GitHub hosting?

My question is:
How do I create a new project in Unity that is not from a template? In Unity Hub, I’m forced to choose a template that may contain packages I may not use.

My problem is:
Hosting a game on GitHub requires a game to be under 25mb. A blank 2D mobile core template build is 13.1. However, Brotli and Gzip compression formats throw and error in GitHub. Research says to tell me to change my Publishing Settings > Compression Format to Disabled. Now my build is 66.8mb, which is too large to upload to GitHub!

if you look at unitylaunchpro that has a way to help you make a template that is litreally nothing you can then add in what you want, the other option is, make a new project, strip out everything you dont ever ever want, from all the built in packages that people ignore, all the additional unity packages evertyhing, make sure you’re on unity 6 to remove the logo etc… Plus, check your build statistics from the log file to see what is big, and what maybe you can sacrifice or, look into the addressables?

I could do that. So the option to create a blank project is gone in Unity 6?

Well. 100% blank was never an option I recall. But the same almost empty is still there.
