After VirtualBox upgrade to 6.1.18_1

[George Mitchell]

FreeBSD 12.2-RELEASE-p6 r369558
Gigabyte B450M DS3H
AMD Ryzen 3 2200G with Radeon Vega Graphics
American Megatrends motherboard

I'm attempting to run an old Windows XP guest machine.  It dies,
telling me that AMD-V is disabled in the BIOS.  If I go to the WXP
machine settings and uncheck the "Hardware Virtualization" box, it
says I still have an invalid Hardware Virtualization setting and it
won't let me save the settings.  I can't find anything in the BIOS
that looks at all like "AMD-V".  When I wws trying to run this machine
under VBox 5.2.44_1, it crashed FreeBSD, leading me to upgrade to
6.1.18_1 and getting me into the current situation.  Help?
