Yes — in Jain Dharma, women can attain kevalajñāna.

However, there is a traditional difference between Jain sects:

• Śvetāmbara tradition: accepts that women can attain kevalajñāna and liberation.
• Digambara tradition: holds that a woman cannot attain moksha in the female body; she must first be reborn in a male body, and then can attain kevalajñāna and liberation.

So, the short answer is:

• Śvetāmbara view: Yes
• Digambara view: Not in the female body

In Jain philosophy, kevalajñāna is attained by complete destruction of ghāti karmas, and this spiritual capacity is understood differently in the two traditions regarding the female शरीर.

If you want, I can also explain this according to Āgamas, Tattvārtha Sūtra, or the Digambara–Śvetāmbara difference in simple terms.
