People do stuff like obscuring the plate with a bike rack, a magnetic leaf, tinted license plate cover, etc, but it's a risky game to tempt the toll collector like that.
When I lived in Texas, toll roads were just starting to become fashionable. People worried that the toll tags would be used to give speeding tickets, so a law was written preventing police from using that data for that purpose.
Just get a Tennessee plate -- they decided to use a background color with a text color that both show as the same under IR, so most ALPRs can't read them (at night at least). They refuse to change it, last I checked.
