As usual, TIMATIC is the best source of information here. It says (in part):
Visa
Visa required.[...]
Visa Issuance:
E-visas can be obtained before departure at https://indianvisaonline.gov.in/. Passengers using their e-visa for the first time must have:
- a passport with at least 2 unused visa pages, and
- a printed confirmation of the Electronic Travel Authorization (ETA).The Immigration officer stamps the e-visa in the passport with the expiry date of the visa and the number of entries allowed.
So, the answer is that you do not need two unused visa pages at the time of travel unless you are using an e-visa for the first time.
