L2 I-94 extension without leaving the country


My L1 Visa expiry date and I-94 date is March 2019.

My wife’s L2 visa expiry date is March 2019 and her I-94 expiry date is August 2018. She got the I-94 date only till August 2018 because her Passport expires by then. If I renew her Passport, please let me know if there is a way to extend her I-94 without leaving the country.
