Uhh ... not really.
But.
Most drums will have a MAX DIA or Max Diameter note on it.
Obviously, if it's under 10" (under 254mm) then it's a 9 inch drum. Slightly over 10" (or slightly over 254mm) is a 10" drum. (I THINK it's nominally 10.030" or the metric equivalent to that - but that's a darn easy way to tell.)
If your drums don't have that, then pulling one and measuring across the inside is the only way to tell for sure. MIGHT be able to measure around the backing plate ( the circumference ) and see if it's about 31.5" or closer to 28.25" or so (not sure of the exact; that's 10" or 9" circle circumferences). For measuring stuff like that, I tend to use some twine or a cloth tape measure; if I use twine, I mark where it crosses then measure between the marks.
If you decide you want 10", and you don't have but 9" now, you can locate backing plates; pull the axles (note: I'd redo the bearings and seals while they were out!), pull the old backing plates, put on the "new" backing plates, and put all new 10" parts on it.

The 9" typically have fins that are flat, the 10" drums have fins that have a step outward where the drum increases in size, the 9" doesn't have this.

The 9" drums look slightly different from the 10" drums, you should be able to recognize which you have by looking through the wheel. If you have steel wheels that block the view you'll have to take one off.

What's weird is the metric units, but I've found metric parts all over the truck. Super weird for a US vehicle.
Max Dia = 230.0

Yeah I guess that was an era for that. Kinda died didn't it? Wish they would just pick one. Metric = evil IMHO.
