How to execute a single subtest from OpenSSL 80-test_ssl

I compiled OpenSSL 1.1.1k and one subtest in 80-test_ssl_new.t is failing. How to debug this? The test is a test suite consisting out of 29 sub tests. Only sub test 20 is failing: 20-cert-select. Can I somehow run only this specific sub test?

Just running 80-test_ssl_new.t works like this:

HARNESS_VERBOSE=yes make TESTS="test_ssl_new" test

which already generates quite a lot of output and runs all 29 sub tests.

There are instructions here:
