You can use acetone as well, as the effect is stronger. It will begin to neutralize the plasticizers found in latex paint, but will leave alkyd paints intact. Running acetone over the surface of a latex paint will cause it to develop a tacky texture that prevents sliding your fingers over it smoothly, always use non-plasticine gloves for a touch test

For long-term adhesion one should use an orbital sander on the oil paint, then wash the surface with a TSP solution, and then use a latex paint primer. Only after these steps are taken should you apply two coats of latex paint. It’s a pain in the ass that uses more materials, but it can be done. It’s about the same amount of work as just stripping and repainting with latex from the wall up
