UnityPlus - remove splash screen - minimal Unity version

Hi, I want to purchase UnityPlus version to remove default splash screen from my game. However I still work on Unity version 5.3.6. Will I have an option to remove splash screen on this version on Plus tier? Or do I have to update my environment to 5.4 or 5.5?

(Sorry for the necropost)
As far as I know this has been possible for years, so you’ll have no problem with disabling it in 5.3.6.
