Good afternoon. Is there any way to regulate the speed in a three-phase motor with a single-phase regulator?

You can't .. !!! In industrial electricity, you have to use a frequency converter.

Thanks for your answer.
Could it be that a speed regulator with 220ca input and three-phase output is marketed?

If there are with 220V single phase input and 220V three phase output.
If your motor is 220/380 three-phase, you connect it in delta to 220V three-phase.
The link shows one of that type.

There are several models of single-phase and three-phase input inverters that you can use for what you want. These drives can be programmed so that the output is three-phase 380v or three-phase 220v. The benefits they offer are very varied such as progressive start, maximum current limiter. power compensation according to speed, analog speed selection using potentiometer, etc.
