To my knowledge the answer is no, these old releases are no longer receiving updates after their expiration date.
See also this article about expired Windows 10 versions (general, not specific to Enterprise and Education):
To my knowledge the exceptions to the expectation to upgrade to the new releases in a somewhat timely fashion are the long-term support versions (LTSB/LTSC), like Windows 10 2016 LTSB and 2019 LTSC.
(Essentially long-term support versions for the desktop based on the same Windows codebases as Windows Server 2016 and 2019).
