The bossy main verb "have advocated" must be followed by a noun phrase beginning with "that." Within the "that" phrase, we need a subject ("parents") and a command subjunctive ("discipline"--the infinitive "to discipline" minus the "to").
Both of your sentences have the required elements:
Popular child psychologists have advocated that parents discipline male children as they would (discipline) daughters.
Popular child psychologists have advocated that parents discipline male children as they discipline daughters.
Thus, I think "would" introduces a meaning difference rather than a grammar issue. "Would" is hypothetical: sentence #1 would be better addressed to parents of sons but no daughters, sentence #2 could be addressed to parents who have both sons and daughters.
