[Success] - Big Sur on Gigabyte Z97X-UD7 TH Core i5 HD4600 Graphics

Success! Using my 2015 Gigabyte Z97X-UD7 TH was able to update to Big Sur. Tried multiple methods and the only one I found that works flawlessly was:

1. Using OpenCore 0.6.4 follow guide to install Catalina
2. Boot into Catalina and download Big Sur from App Store then install

Trying to install Big Sur from a boot disk did not work, would crash the installer at 12mins left.
