Find out & update a particular IP in multiple SGs on AWS

Wanted to list the SGs of a VPC that has a particular IP whitelisted. Update this IP to a different IP in all the SGs that contains it or create another rule in those SGs to add a new rule with the different IP.

Example:

 Consider 1.1.1.1/32 is present in 3 different SGs of a VPC namely: sg1, sg3, sg7.

Out of a total of 10 SGs in the VPC, wanted to list & identify the 3 SGs that have the IP 1.1.1.1/32 whitelisted.

Trying the same via AWS CLI. Any help would be appreciated.
