Hello,

is there a way to disable this limitation?

"If M2_1 is occupied, PCIE4 will be disabled."

For me at the moment this is a harsh limitation - who thought of something like that during the design of this board?

according to

https://www.asrock.com/mb/AMD/B450" rel="nofollow - https://www.asrock.com/mb/AMD/B450 Pro4/#Specification

AMD Ryzen series CPUs (Vermeer, Matisse, Cezanne, Renoir, Summit Ridge and Pinnacle Ridge)
- 2 x PCI Express 3.0 x16 Slots (PCIE2: x16 mode; PCIE4: x4 mode)*

4 x PCI Express 2.0 x1 Slots
Supports AMD Quad CrossFireX??and CrossFireX??*

*Supports NVMe SSD as boot disks
If M2_1 is occupied, PCIE4 will be disabled.
