[Request] MSI X350 Tomahawk AM4 PCIe 4.0 Unlock - possible?

Hello,
I bought an X350 Tomahawk and I was wondering if it is somehow possible to unlock PCIe 4.0 on that board or chipset rather. I remember first (beta) versions of AGESA that came out around zen3 release unlocked pcie 4.0 functionality but later on got blocked again by AMD. Is that something you guys could do?
I’ve absolutely no idea how to do that and if it’s even possible. I just found this forum and saw here are some people who are willing to help out random internet people, wich is amazing. Neither I have any idea what kind of magic you guys are doing, but I just wanted to kindly ask if anyone can help me out with that? It would be awesome
