Here 2.5 wild guesses:

If it is about "pushing around" a raster map (no squeezing):
- https://grass.osgeo.org/grass78/manuals/r.region.html

If a rotation is needed:
- https://grass.osgeo.org/grass7/manuals/addons/i.rotate.html

If it is about a real transform:
- convert the raster matrix to its vector center point representation; then
- https://grass.osgeo.org/grass78/manuals/v.transform.html
- rasterize again

But again, just some almost random ideas.

best,
Markus
