This doesn't need to be quoted

This matches what we do on dozens of pages.

I like what you did here of calling it a module continuously.

Oh, I just copied this from nvmf_tcp.4 which uses the same markup. Presumably these nits need to be fixed in that.

Hmm, grepping in share/man/man4:

> git grep '_load="YES"' | wc -l
     504
> git grep '^\..*_load="YES"' 
acpi_wmi.4:.Dl acpi_wmi_load="YES"
mrsas.4:.Cd mrsas_load="YES"
rtsx.4:.Cd mmc_load="YES"
rtsx.4:.Cd mmcsd_load="YES"
rtsx.4:.Cd rtsx_load="YES"
u2f.4:.Cd u2f_load="YES"
umb.4:.Cd umb_load="YES"
vmm.4:.Cd vmm_load="YES"
wpi.4:.Dl if_wpi_load="YES"

Given the description of .Cd in mode(7) it seems like it should be used for device foo but not loader.conf entries.

Also, existing pages (which use prose) still indent these lines via a \.Bd block which I think we are stuck with until we settle on a format that doesn't use prose.
