Can you delete WG account to get back into games vs bots?

So I'm almost done with the plat for this game, but I'm missing one trophy that I'm struggling to unlock. I still need the 4 kills in 1 game with a certain faction. I was wondering if I could delete my wargaming account in the settings to go back to Standard battles vs bots to knock that trophy out easily (since its gonna be the last one i need for the Plat)
I don't have any way to test this out atm and wasn't able to find a clear answer anywhere.
