Answer

No. As per publicly known and accepted Jain tradition, Acharya Vidyasagar Maharaj is not known to have attained Keval Gyaan.

He is deeply revered as a great Digambar Jain Acharya, tapasvi, scholar, and spiritual guide, but Jain tradition has not recognized him as a Kevali.

Explanation

Keval Gyaan means perfect, infinite knowledge attained after the complete destruction of the knowledge-obscuring karmas and other related karmas. A soul with Keval Gyaan is called a Kevali.

In Jain Dharma, such an attainment is extremely rare and is not declared casually. It must be clearly established within Jain tradition.

Acharya Vidyasagar Maharaj is honored for:

• strict Digambar monkhood,
• deep tapasya and discipline,
• scriptural knowledge,
• inspiring countless people toward Jain values,
• extraordinary simplicity and renunciation.

But reverence for a great saint does not mean that he had attained Keval Gyaan.

Takeaway

Acharya Vidyasagar Maharaj was a highly revered Jain Acharya, but he is not regarded in Jain tradition as having achieved Keval Gyaan.
