Where is there a classic car insurance for under 25 year old drivers?

Hello, I want to allow a vintage car, but I am only 21. I have already read through several pages of insurers who also had interesting offers, but unfortunately I am discriminated against everywhere because of my age, all the vintage car insurances I have found seem to want to insure only drivers from 25. Really sad that such a thing is allowed. Does someone know a vintage car insurance that would insure me?
