Can my spouse stay in the US when her passport is submitted to the dropbox for h4 renewal?

Our H1B and H4 visas expired. However, the extension has been approved. I have I129.
I have scheduled an appointment for visa renewal, and the US consulate in Mumbai has offered the dropbox option. Can my spouse stay in the US while I travel to India to submit her and my passports to the dropbox? Or does she has to leave the country physically even for the dropbox option?

You cant apply for US visa while the beneficiary is physically present in the US.
