Is it acceptable to make a non-master branch a standard branch?

Question

git

Once upon a time there was a repository with a single branch - master . It contained a solution to the problem using a multilayer perceptron. Then it was found out that a multilayer perceptron is not very suitable for this task, and a CNN branch was made with the solution of the problem using a convolutional neural network.

Now the solution in the CNN branch does a much better job than the solution in the master branch , so the solution in the CNN branch should be in the standard branch. In addition, I also want to leave the solution using a multilayer perceptron.

Is it possible in the repository settings on the github to make the CNN branch standard, and the master branch- not standard? It is clear that in any case it is possible to do this, but is it customary or is it to do so? Is this a good solution?

What's wrong? Take it and do it.
