Partnershipfirm's incometax return filing via., aadhaarcard

is it mandatory for one of the partner's to use digital signature for e-filing Partnership-Firm's Income-Tax Return ?
can't he use his aadhaar-card, for his partnership-firm's Income-Tax Return ?

(like he uses his "aadhar-card EVC" to file partnership firm's GST Returns)

if yes; that can you provide me any official-link of the income-tax website which states so ?
