On a personal level I don't particularly care one way or the other.
I don't dislike voice acting in games and I don't think it "severely limits options" for dialogue, either (I feel like that's a complaint that belongs to the past and just doesn't fit a production of this size and budget).
At the same time I don't give a damn about your custom MC in particular reading his lines aloud.
What I can barely stand in BG3 and hope to see addressed to some extent, on the other hand, is the player character over-acting and over-reacting with stupid silent expressions like the most insufferable street mime.
