The extension block has a vendor-specific data block with AMD's vendor ID. Since it's not publicly documented, I don't know what all the bytes mean, but it seems to have the FreeSync range in there. CRU doesn't have a way to edit the data block directly, but it can import hex data from text files.

I formatted the .txt file to group the data blocks and resolutions:
  edid.txt (Size: 789 bytes / Downloads: 630)

Look for this line:
68 1a 00 00 01 01 28 4b 00

Hex 28 = 40
Hex 4b = 75

Try changing those numbers (30-75 Hz would be 1e 4b). Then import the text file using CRU.
