Can change of employer is possible during Cap-Gap?

My H1B got picked from the Employer 1 but still did not get an approval notice. OPT EAD has been expired in April 27.

However, I got a new job offer from Employer 2 and i want to move to that before the approval notice or if it is approved before the start of my H1B i.e October

My current work status is OPT/CAP-GAP My question is Is it possible to change the Employer to Employer 2 and can work for Employer 2 during cap-gap period in my case?

Kindly respond to my question asap.

thanks in advance.
