Is there a way to get rid of EPS connector?

Hello everyone, I currently have 8x5700 XT setup but i’m planning to move up to 12 GPU’s.However, I only have 12 total PCIE & CPU sockets on my PSU’s. So, one of them is taken by CPU package on my motherboard. I wonder if there is a way to power CPU diffrently so that i can free up that socket and use it on the 12th GPU. Thank you in advance. My hardware is as follows.

GPU’s: 8 x 5700 XT (12 if i can solve this issue)
MB: Biostar TB250 BTC PRO
PSU: 2 x Corsair HX1200 with 6 pcie connectors each.(only comes with 4 tho)
