Yes for further research look into contralateral training (but it does also go by a few other names) or the phenomenon of receiving/maintaining muscular benefits (hypertrophy and/or strength) when only training the opposite side.
Meta-Analysis for in depth of all the research if you care about the how and why:
There is solid evidence on the cross-training phenomenon, but the training load required to achieve it has yet to be established. The aim of this meta-analysis was to deduce which unilateral strength training load (duration, frequency, intensity, rest ...

Conclusion:
Some research on possibly why that also highlights benefits to “visualizing” doing the movement as well:
The present review proposes the untested hypothesis that cross-education performed with a mirror increases the transfer of motor function to the resting limb compared with standard cross-education interventions without a mirror. The hypothesis is based on neuroanatomical evidence suggesting an...

One study showing benefits in muscle size (not just strength):
The purpose of this study was to apply cross-education during 4 wk of unilateral limb immobilization using a shoulder sling and swathe to investigate the effects on muscle strength, muscle size, and muscle activation. Twenty-five right-handed participants were assigned to one of three groups as...

I’d keep in mind:
-You will probably lose size regardless (and strength).
-Your training will be limited.
-It is possible to keep some of the performance/gains with this methodology, but some of the biggest benefits here is it will help lessen the detraining to potentially allow return to baseline faster.
-Don’t stress about it though, even if you don’t do anything gains come back quick and it would be worse to over do things both mentally and physically, a break may be good.
