Can I remove FRP with Heimdall/Odin?
The answer to your question is no.

Without a Samsung Engineering firmware load that has adb and USB debugging enabled in the setup wizard this is not possible, and I have never seen one leaked out for any Snapdragon based S7, so the answer is simply no.

Remember, FRP is DESIGNED not to be able to be bypassed or defeated, every time a exploit comes out, it get's patched, and this device just got another security update this month.
