For VGA no. For VBE 3 there are various utilities to change the refresh but most if not all games use VBE 1 or 2.
You could possibly modify the video card bios.

DOS games are typically 70hz.

Also just like today games can use the refresh rate for timing.

Most LCDs can do > 60hz at lower-than-native resolution.
My 1080p does exactly 70hz in an aspect-corrected 1024x768, which is perfect for gaming in DOSBox.
Yeah, the image isn't perfectly crisp if you get close enough, however the benefit of playing judder-free 70 fps in Wold3D and Pinball Dreams is worth it.

Right, but if you are using DOS box you already in windows so it’s not really the same thing as I was asking in terms of pure native DOS

Most games just use standard VGA modes, which are either 60 or 70 Hz, depending on the exact mode. This is because the VGA standard had fixed refresh rates.
