Not that I know of.
Here is the problem, the body adapts to the stresses imposed upon it. You have some kind of baseline strength that erodes very gradually over the years, but that is reinforced and maintainted by whatever your daily levels of activity and genetics will support. If I put you on bed rest except for one training session a week, you probably would not stay at 225 for 3x5 on the squat for very long. The higher you push your numbers, the more stimulus is required. While you may elevate that baseline strength somewhat, once the stimulus is removed, the body adapts to the lack of stress. In general, you cannot train and claw your way up to heavy weights and then maintain that with relatively easy, infrequent training. I certainly cannot. On those occasions that I train once per week for a few weeks, my loss of strength is precipitous.
Training once a week is better than training zero times per week and it will help preserve your progress. However, be not surprised if you lose strength as the weeks progress. If this does not happen, I would be very interested to know about it.
