You can do the same on Firefox (at least developer edition). I thought that you want to do that without going to incognito mode.
So what I do is, I google, right? First page that comes up references how to fix the problem on both Firefox and Chromium-based browsers.
So on Firefox, I have to type the config page, then search for ocsp, then disable it. Then, I can finally access the webpage, but of course, I should remember to re-enable it after I'm done on the misconfigured server.
On Chrome, I can fire up an incognito window, type a magic keyword, do what I need, close the incognito window and go back to default.
Honestly, the latter is a vastly better experience in my world (I do backend/integration dev, mostly Python nowadays, probably a FE engineer will not care either way).
