MS2024 rolling cache limit change

I have tried many ways to try to change the limit of the rolling cache in ms2024 but the limit is 16gb and regardless on what I try I can't change it. The 16.0 gb seems fixed and I can't delete or place the cursor to change it. Hopefully can someone explain to me in steps how to do this? I have tried using the default cache file and my normal cache file on my fastest drive with no success.
