Question Would my Build Support PCIEx16 splitting into PCIE x4/PCIE x1 slots?

[Gamefreaknet]

I intend for this server to be for a BeamMP server (BeamNG drive multiplayer) which notably demands a lot on single core performance and from a few sites and the mobo prices the 11600K fitted well (for a 12th gen or 13th gen mobos were around £200ish). Can I confirm if this mobo will support PCIE x16 Bifurication or not (splitting into "smaller" slots):

[IGNORE GPU SINCE I DO NOT INTEND TO USE AND WAS JUST LISTED SO OTHER PCIE DEVICES WOULDNT USE THE X16 SLOT FIRST BY DEFAULT ON THE LIST]

Nothing in the manual, I would guess no.

Theyll usually be explicitly mentioned in the specs. So yeah, most likely not.

Example of supported Bifurcation mentioned in the specs are like this, on Asus Proart Z790-CREATOR:
