You can use Javascript to change regular folder icon to custom one.

Thanks for the answer
But I believe that is not possible in modern design. May I forgot to say that it is a communication site and there are not script editors in the communication site.
It would be possible by writing an extension the problem is not just one library but several and more to come.
I am afraid that there is no way to customize the folder icon yet!

You could use this for script editor webpart

also you could try using powershell to update multiple libraries at once.
