If it doesn’t have an “End of support” date that means EOS has not yet been announced. EOS is usually announced 6-12 months prior to the EOS date. Since 9.2 was released almost 4 years ago now and 9.5 has been available for over 2 years, I would expect an EOS announcement to come soon, so I would assume less than a year left of 9.2 support.
