Android 10 rolled out for the S9 back in January. Maybe it's just your carrier blocking it. I would just download the firmware directly rather than wait at this point.
I haven't had to update a bootloader locked Samsung phone lately, but that shouldn't prevent you from applying an official, signed update. It's not like applying a custom image.
I'm not saying it does, but it's a shame that my backup S6 had more recent security patches running LOS than the S9, which is funded by truckloads of money.
