BudsGunShop.com - Round trigger

Honestly flat triggers have an advantage putting allowing the finger towards the bottom of the trigger more leverage allowing a cleaner ,easier and more precise shooting experience in my opinion , but yes you can buy a standard trigger and install it or have your local gunsmith do it for you

You absolutely can get and install (or have installed) the rounded trigger if that suits you better.
