How to specify aws creds to connect to multiple clusters in different aws accounts concurrently ?

[ashutoshxhq]

I am building an application where I need to concurrently connect to multiple clusters which will be in different aws eks clusters.
If there a way to provide aws access and secret keys which could be used for getting the auth token.

Currently I think its being picked from envs, which will only allow me to work with just one account per server.
