Is it possible to speed up evolution

Yes. You can speed up evolution through drift (and possibly
selection, depending on population size) by increasing the
mutation rate. You can also sometimes increase the rate of
evolution through natural selection by changing the
environment in a way that increases the heritability of
fitness differences among individuals.

My model says yes

As environmental adaptation increases , stabilizing
selection increases and directional and diversifying
selection decreases (evolution slows down)

decreases and directional and diversifying selection
increases (evolution speeds up)

One way to speed up evolution is to shift that species into
directional or diversifying selection. Put the evolutionary
pressure on high.

(Yet there is a limit to that speed - and that is the rate
of mutation)

(Though us humans can speed up through cultural changes -
which is much faster)
