HP BIOS keeps modifying boot order

ProDesk 400 G4, Z240, ProBook 640 G2, ProBook 650 G2, any HP product with modern BIOS
Other

So far, this issue has occured on HP Prodesk G400, HP Z240 and HP ProBook 640 and 650 G2, on many devices, every time BIOS related.

When I try to disable IPv6, since our organisation uses IPv4 to boot on Network and IPv6 may take quite a long time before timing out, I sometimes get a bug where after saving and quitting, IPv6 will not only reappear in the boot order, but also make another option disappear, such as IPv4 or SATA. I can then return back in the BIOS, disable the (now 2?) IPv6 settings, enable back IPv4 or SATA, save and quit, and find the same issue after.

Also, I could sometimes get IPv6 disabled with SATA and IPv4 but then after failing to boot on IPv4, the boot order would bug and replace SATA with IPv6.

To fix it, I have to either hope it works or reset BIOS to factory settings and reapply the desired settings.

 

BIOS version is up to date, using UEFI, Legacy disabled, secure boot disabled.

 

I couldn't find anything related to this issue, and wanted to know if there was a fix other than keeping IPv6 enabled, if HP was aware of this and working on it.
