If you can get the full binary EDID from your monitor, you can edit it with
something like Custom Resolution Utility (CRU) via wine. When importing the
original EDID file in CRU, enable/check "Import complete EDID". After adding
the desired refresh rates/modes, you can export the EDID to a new file (e.g.
"/usr/lib/firmware/edid/your_edid.bin"). Then add the new EDID to your kernel
boot line by adding "drm.edid_firmware=edid/your_edid.bin", which will get
applied after a reboot. You can also try loading it directly and simulating a
hotplug on your monitor. See here for more information:

Custom Resolution Utility (CRU) via wine seems to work fine for me, but it may
not work for you, so your mileage may vary.
