You can use harder rubber compounds but that's a non-starter because longer stopping distances.

It is common for electric cars to use harder rubber compounds in their tires. Not because of particulates, but because tire noise is particularly noticeable in an otherwise quiet electric car, and because tire life is a concern for EV drivers.

Luckily, both reduced noise and increased life are fairly well correlated with reduced particulate emission.
