No.  That configure option will disable the consistency check between
the headers and library versions at compile time, ie the API.  It was
added when some vendors (from memory, Apple) started shipping
libcrypto updates without the corresponding header updates.

This diff posted affects the check between the version it was compiled
against and the currently installed library version, ie the ABI.
OpenSSL improved the ABI compatibility from "must be the same minor
release" in 1.x to "must be the same major release" in 3.x but we
currently only have the 1.x checks.  Damien had a slightly different
diff that also fixed this, not sure what happened to it.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
