Canopy ejection for late war La-5FN?

[Kubert]

Did the later La-5FN series have emergency release mechanism for canopy? According to information in the Museum, they were modified from series to series. And since the La-5F already has it in Kuban, is there a possibility that the La-5FN will receive the same upgrade option for the 1944 Odessa/Leningrad career?
