Hiding the header on multiple templates

[TLP0]

Looking for some guidance on how hide the header on more than just one template. Currently, I'm using the 'unless' condition to remove the header on a template we use for opt-ins, however, I had to create another template used for a video (page.masterclass-no-header) but I can't figure out how to add that template into the code. Everything I've tried removes the header from all templates including the homepage. 

Here is what I currently have:

TYIA!

This might seem like a bit of a hack but if your Unless statement is working for you I think you can just use an OR operator. This would get a bit much if you kept adding templates but for a couple it should be good:

{% unless template == "page.opt-in' or template == "new-template-you-want-to-exlude" %}

Thank you, Steven! That worked! I appreciate it!
