No. In Jain tradition, Bhagwan Parshvanath is believed to have attained Keval Gnana, but Manahparyay Gnana is not generally attributed to him.

So the accepted view is:

• Keval Gnana: Yes
• Manahparyay Gnana: No, not usually stated for Bhagwan Parshvanath

In Jain scriptures and tradition, Keval Gnana is the supreme and final omniscience attained by a Tirthankar. Manahparyay Gnana is a special knowledge of the mind, usually associated with highly advanced ascetics, but it is not commonly listed among Parshvanath Bhagwan’s attained knowledges.

If you want, I can also explain the difference between Matijnana, Shrutgnana, Avadhijnana, Manahparyay Gnana, and Keval Gnana in simple Jain terms.
