I can't believe people are suggesting adding weight via the wheels or the cassette, these are the absolute worst places to add weight on a bike, especially if you are racing.
Get an off cut of some roofing lead, thin it out and cut it as needed, then bend it around the seat/down tube, near the BB and zip tie it in place

If you're gonna add weight, seems pointless to add lead. You might as well go for deep aero wheels, aero bar, aero seatpost, etc. At least then the extra weight is doing something for you.
Unfortunately this is a rule that is rarely enforced. In some 20+ UCI races my son didn't get his road bike checked once - except in the USA.
But as he normally runs quite under weight the best for him is getting a fishing weight and pounding it out with a hammer and attaching to the BB.

He also went from an alloy cassette 125g to a steel Ultegra. That helped.
The cassette is essentially non-rotating weight and he prefers it over being higher on the bike as in the seat tube. We also went to heavy steel skewers. In the end we added about 800g. That is with his super light 50mm profile /25mm wide, 25mm tubs wheels (except with the heavy cassette).
Note that the lead, skewers were easier to remove for Belgium/other non-UCI races - while the cassette took a few min.

The BB is several centimetres lower than the wheel axle. Therefore if you can drop lead down the seattube so it's sitting on the bb shell the CG will be lower than if you added cassette weight.

We did both. Dropping things down the tube - rattles. Esp as so many races have cobbles.
And had some weight in the left bar end mirror. https://1drv.ms/i/s!AoUfGFf09F_flbcKGsaraULC4-kItg
