I work as a system administrator and I have several servers on the B650D4U motherboard and two of them freeze after the GRUB menu, this happens with any OS in EFI mode. The problem is not that there is no picture on the ipmi, but the problem is that the server freezes, since our company has a live cd image for diagnostics, which can be loaded via pxe and connected via ssh. When the BIOS is set to legacy, everything works, there is a picture, the live cd image for diagnostics is loaded, you can also install any OS without problems, i.e. the problem is directly in EFI mode, most likely in the video adapter when the graphical shell of the image is loaded, including Windows 2019. In Linux, I tried disabling or enabling some modules in the kernel - it also did not help, I tried vga=normal, video=vesa:off, video=efifb:off nomodeset
I tried configuring iommu and gfx, also debugging via serial over lan, I used the boot parameters console=ttyS0,115200n8 console=ttyS1,115200n8 - there is no activity in serial over lan after the GRUB menu.
Flashing the BIOS and BMC to the latest versions did not solve the problem, other servers with this motherboard work without problems.

what it displays if you try to boot OS from GRUB shell (also called the GRUB rescue or command line)?

if it boots the kernel what are the logs? (dmesg,journal)
