Welcome to maker.pro.
If the maximum Wattage W for the complete drone is known you can estimate the total maximum current drawn by the motors as W/3.7 Amps. Divide that figure by the number of motors to get the maximum current per motor. This assumes the motor currents account for most of the battery current.

If it's weight is about 3 grams ,4 to 6 watts of power at 3.7V,
70000 RPM. 200mA, maybe one amp at Max. I pulled that out of blue sky. Lots of nieces and nephews and stuff buzzing around the house "drones".

One would naturally ask, why do you need to know, however, it's a simple process to connect an ammeter to the battery.
As they say, suck it and see.
