That's not how it works.

Good Grief.

"A virus that is widely circulating in a population and causing many infections has more opportunities to replicate and thus to mutate

While it's not possible to stop SARS-CoV-2 from mutating, health experts say it is possible to reduce the chances that a new and more deadly mutation will arise by limiting the virus's spread. This is why public health interventions like wearing masks, physical distancing, and vaccinations are important: they reduce the total number of times the virus can replicate and therefore the chances that it can develop a more dangerous mutation."
