Can I use Dove shampoo daily to clean the scalp 2 months after hair transplant?

Ask you doctor for their specific post operative care instructions.Any shampoo may be fine but your doctor (who performed your surgery) may not agree.

At 2 months post transplant you may resume your normal hair care routine, including the use of your preferred shampoo, conditioner (if you need to use it), hair gel, etc. The transplanted hairs, although not grown yet, are already healed and will start to appear soon. So feel free to enjoy your new hair, and don't worry about anything.

Yes you can use Dove shampoo at this stage after a hair transplant. It is important to keep your scalp clean, healthy and moisturised. A few moments of scalp massage when you shampoo will also stimulate the blood supply.
