Yes.  There are two settings in the DOS box:  DOS_HIGH, and DOS_UMB.
Set them to "yes".  You might also want to locate the DOS= line in
CONFIG.SYS, and be sure it is set to HIGH,UMB.

You don't have to include any HIMEM.SYS or EMM386.SYS drivers.  The
DOS emulator handles all that.

This being done, DOS will load into the HMA, and LOADHIGH should work.

Then use the system settings instead of the DOS= line.

If you're using a specific DOS session (image file boot), then after
loading FSFILTER.SYS, you should have a DEVICE=C:\OS2\MDOS\HIMEM.SYS
line.  This is in addition to the DOS settings.  Note that this driver
is only required for specific-DOS sessions.
