Short response, no you will be fine as long as you respect the archery hunters that are obviously actively spotting and stalking antelope.
Long response, I don't know what units you are looking at or where you are from or your antelope hunting experiences but your scouting will and should be 99% from roads. Antelope are not (usually) hard to find and your scouting should be focused on driving roads and verifying what roads are and will be open during your hunt, glassing locations, access points, Block Management access, BLM access, State access, etc. all while glassing and looking for antelope and noting those locations. If you see other hunters looking at antelope mark that location and move on and let them do there thing, maybe even talk to them and they may have some insight on the unit being they cant hunt it during the rifle season. Another .5% would be walking to vantage points that you e-scouted that may give you an advantage for glassing, etc. And the other .5% would be learning the layout of the land and surrounding city, how far is the nearest gas station? Ice? snacks? hotel? camping spots? Hopefully this provides some insight, having hunted a handful of units from west to east in Montana feel free to PM if you have any specific questions.
