From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

You want to look into modifying your display EDID.
I don't believe there's a GUI for this on Linux but this post referencing the Archwiki might come in handy
https://foosel.net/til/how-to-override-the-edid-data-of-a-monitor-under-linux/
In this guide author dumped edid from disaplay and then loaded it without any modifications. So after reloading edid you can choose any resolution? Or I understood something wrong?
I think you'd have to modify the edid, since you're setting a custom refresh rate, not a hidden one.
I've use wxEDID to force enable VRR before.
