Still no.

Strictly speaking, organisms don't evolve at all. Populations evolve. And of course evolution requires some form of variation.

(Specifically, I am reffering to "minimal cell" organisms, and
ignoring [stricktly enforcing] mutation to their genome)

That's a problem. Even adaptation (different from evolution) would seem to be beyond a minimal cell. Evolved flexibility is one sort of adaptation, but it isn't evolution and wouldn't happen in a minimal cell. Recombination is a possibility, but there are two problems with this: 1) minimal cells wouldn't be capable of recombination and 2) you need some variation in the population, and how did it get there if the genome is preset?

Further, I am implying that (If we allowed for mutation [which we
don't] those mutations are filtered out by whatever means)

Then no evolution is possible. Please explain.
