The easiest way of acquiring a Dubious Disc in Pokemon Unbound is by exchanging it for 32 Battle Points at the Exchange Service Counter of Battle Frontier. You can do this as soon as you gain access to the Battle Frontier in Seaport City.
Alternatively, you can also obtain a Dubious Disc by collecting it from the Seaport East Warehouse, but this method is relatively more complicated and requires partially completing a lengthy side-mission (Mission #071: The Rogue Electivire).
Once-only Methods
Seaport City
Starting at Seaport City’s PokeCenter, follow these steps to obtain the Dubious Disc:
Step 1: Go to the eastern end of the city and use the stairs here to reach the port.

Step 2: Head to the southern end of the port.

Step 3: Enter the warehouse on your left. This is the Seaport East Warehouse.

Step 4: Once inside, the door will be locked with a passcode.
Move to the backside of the first wooden crate on your left and interact with this to reveal the passcode.

Step 5: Enter the passcode to unlock the door and head into the basement.

Step 6: Head straight down till you reach the two blue containers and a couple of boxes at the end of the corridor.

Step 7: The Dubious Disc is hidden on the box in the corner here.
