成唯識論述記 6.590

述曰：此必不俱。見取執為勝，戒取執為道，俱能得淨，順己之境，不憎彼故，故不相應。諸論六煩惱明之，故無二取不俱起失。

The Commentary states: These definitely do not occur together. The grasp of views clings [to its object] as supreme, and the grasp of precepts clings [to its object] as the path, both capable of attaining purity; being objects agreeable to oneself, one does not hate them, and therefore they do not associate. The various treatises clarify this among the six afflictions, so there is no flaw of the two grasps not arising together.
