Does Environment play its influential role on the expression of gene through control of epigenome ? or it has direct control over gene expression- inducing phenotypic plasticity?

I think environment plays its role in the phenotypic expression of a genotype by controlling epigenetic activities. With the variation in the environmental factors, epigenetic control of genome expression varies substantially resulting phenotypic plasticity. Environment, thus plays indirect role in the phenotypic expression of a gene.
However, environment has its direct role in the expression of a genotype only when it causes changes in its composition/structure( Mutation)-Mutagenic effect
