Does H4 COS is required for spouse to apply H4EAD

Hello All, I have approved I140, and my Visa valid till 2023. I got a job opportunity with another company and planning to transfer my H1B to the new employer. My spouse who’s in India with Visa stamped till 2023 from my current employer. Once my H1b gets transferred to the new employer, I’m planning to ask my spouse to travel to the USA and after her arrival, I’ll be applying for H4EAD.

The question is, do I need to ask her to go for visa stamping again in India from my new employer, to bypass (h4 transfer, COS & Biometrics) process so that I can file her H4-EAD immediately after she returns to the USA. I just wanted to check the best and quickest way to file the H4EAD.

Thanks
Mahi
