I too have a Nvidia GeForce 210 [GT218] that only reaches 70Hz with
the 340xx driver.
The issue is the kernel. No kernels beyond 5.4 support the 340xx
driver natively.
Some techies on EndeavourOS found a way to do it with some kernels
using Aur adaptions with NVIDIA-Linux-x86_64-340.108.run.

I haven succeeded yet with Devuan 4.0. So stuck with nouveau's
provided 60Hz. (:
