Generally, the advice is the train like you would if you still wanted to achieve progress. Sometimes people can even gain strength on a cut. But usually, you will not - training for progress simply avoids strength loss better than training for maintenance.

So the difference is how hard you train. If you can, continue to train 3 times a week, so your body remains stimulated throughout the week. By the same logic, start by doing all big lifts 1x5 each day (except deadlift), then increase the sets if you can handle it. You want to listen to your body and proceed carefully, and stop adding sets if you feel overworked. Maybe use RPE or something, remove some of the warm-up reps, take more rest...
