May I suggest revolution?

There is no effective technical solution for political problems. If you find one, it will soon be outlawed or rendered ineffective (eg if you wear mask and sunglasses, prepare to be harassed by law enforcement). Lobbying to stop unconstrained surveillance is the only option.

You need to own a few copies of face recog software, and practice with face restructuring latex makeup which gives you a new realistic face with a new bone structure.

Change walking gate. Get shoes with small platforms to change height, learn to walk naturally on those.

Change mannerisms.

It's doable, but a major pain to pull it off.

Like imagine quickly applying the latex makeup, walking in front of your own identical face recognition camera at home, take everything off, rest, repeat, 10 times a day, 300 days a year, for 10 years. Until it is second nature. Now you can rely on this to do serious work.

You have to create a new person, basically. Assuming you practiced well and tested everything against real software, you can now be a different person for some hours in a reliable way. Once your secondary identity is exposed you'll need a new tertiary identity. Never do anythiny fishy as your base identity.

The real solution is political, like everyone else has said. Because you won't be able to fool the system casually without a massive effort and practice, practice, practice on your own property first, before you rely on this for real work in the wild.

Handheld scanning infrared laser, 5 to 50 watts Basically laser-clean the sensor out of existence

Horse mask should work

IR blocking sunglasses are the simplest and most practical solution.

Facial recognition systems compare the distance ratios between your eyes and nose primarily. Hiding your eyes is very effective towards fucking that up. A mask alone is typically not enough.

Mask, sunglasses (and glasses that block IR), slight deviations in movement patterns, and GETTING OUT OF THE CITY.

A hammer?

You learning how to make other people directly around you care. Start with the easy stuff, like helping them leave WhatsApp and Discord.

IR LEDs around your hat or glasses but I believe some cameras can filter out IR.

For surveillance cams:

Cover them up and destroy them with drones.

Mask or neck gator, dark shades, toboggan hat or head scarf/wrap that covers your ears. Ears are just about as identifiable as fingerprints.

Artillery strikes on the data centers

mask with dark sunglasses or a ski mask with dark sunglasses
