For several types of certificate and ssl issues(HSTS , blacklisted/revoked certificates) that option is hidden and thus unavailble. Chrome can be a stickler, which is understandable as the majority of its users are not prepared to deal with the possible downsides of going to an untrusted page.

So this is where the "cheat code" comes in handy:

https://subdomain.preloaded-hsts.badssl.com/

https://pinning-test.badssl.com/

Then there are those which have no "cheat code" bypass, so you'd have to use some other method:
