Hello! My name is Mostafa, and I will try my best to assist you with this so that you find a satisfactory solution.
Unfortunately, there is no built-in feature in Windows for this. You can change DPI, as you mentioned.
Some third-party tools may be available that can help you adjust the resolution and scaling settings for individual apps. One such tool is "Borderless Gaming,"
You may send feedback or suggest a feature to Microsoft thru this link:

I hope this help, reach out to me, and I will be happy to help and try my best to resolve your issue. Thank you.
Best,
Mostafa
