Can you sneak in a raspberry pi? Maybe install pihole, eblocker, adguard home, or technitium on it and point your PC DNS settings to it? Requires hooking up another device on the work network, idk how locked down you’re network is, but it’d be sweet if you could do that.

I run everything at work. I’ve got 3 raspberry pi’s I run for redundancy and block ads for everyone at work. Occasionally, one of our teams complain because they’re searching a product on Google and clicking the top link that’s an ad, so I just whitelist their PCs from blocking. It’s annoying they’re so set in their ways, like find another link that doesn’t say sponsored, but oh well. Best of luck.
