'Generate Random String with Specific Restrictions

Tring to generate a random string but it needs to be formatted a specific way.

N = number L = Capital Letter

must be NL-NN

needs hyphen as well

examples: 5K-22, 9L-19, 0R-66

every method I have tried has just generated a string but without the hyphen, I know it is probably something simple my brain just hurts thinking on it so I thought I'd see if one of yall could give me a hand.

Thanks
