The lack of selection pressure wouldn’t result in “devolution” but rather a lack of change in the frequencies of genes.
Even in the absence of selection pressure, Hardy-Weinberg equilibrium only holds in an infinitely large population with no mutation. So I think no.
In a real population with no selection pressure, you would expect to see allele frequencies change somewhat more frequently than they do in a population undergoing adaptive evolution—google “neutral theory”.
