After 1. e4 e5 2. Nf3 Nc6 3. Bb5 a6 4. Ba4 d6 5. O-O the move covered by all authors is 5...Bd7, with some covering 5...Bg4 also. Another move is 5...Nf6.
As mentioned on this thread, 5...b5 is another option. Also 5...Be7.
Lajos Portisch wrote My Secrets in the Ruy Lopez. Many of the games he analyzed include an early ...Be7, on move 3, 4 or 5. Many feature an early ...d6 and ...Bg4, holding the pawn on b7. Many of the games are in the Modern Steinitz by some move order. If you want a structured look at the opening, it can be maddening. On the other hand, if you'd like to broaden your thinking -rejecting dogma, this may be like a breath of fresh air.
Most, perhaps all, of these games were played before computers got so strong. That's not so bad. Fischer studied Steinitz and Carlsen knows the classic games of the past. On the other hand, Nakamura said he never owned a chess book as a child.
I think most of today's masters and grandmasters use computers and strong engines. I find it interesting when GMs get it right in published analysis and computers get it wrong for several moves until, following along, they "get it." I suppose there are various explanations including tactical vision catching up to the result of strategical thinking.
