Reset Private Mode pattern?

[Skeletor_118]

On my Galaxy S6, I am trying to figure out Private mode, and I have entered it by putting in my PIN code. However, I have long forgotten the pattern I made for Private mode, and my phone will not give me an option to enter my PIN to change the pattern or use any other method to enter Private mode. Is there any other way to change or reset my pattern for Private mode?

if you draw the wrong pattern several times in a row it will ask you for the pin
