How to migrate from v1 credentials ChainProvider

[BananZG]

Currently in our code we have a list of credentials.Provider defined with V1 SDK, something like:

sess, err := session.NewSession(&aws.Config{
    Region: aws.String(region),
})

endpoint := "" // example : some url
profile := "" // example : lambda_role
sess.Config.Credentials = credentials.NewChainCredentials([]credentials.Provider{
    &credentials.EnvProvider{},
    &credentials.SharedCredentialsProvider{
        Profile: profile,
    },
    &ec2rolecreds.EC2RoleProvider{
        Client: ec2metadata.New(sess),
    },
    endpointcreds.NewProviderClient(*sess.Config, sess.Handlers, endpoint)
    // .... and so on
}

in this way, we are able to deploy same code to different environments that read credentials in different way.
Locally different devs have different ways to run their code too, some with aws-vault's ecs, some with ec2, some just run the command directly with custom profile.

Now with V2, if I defined all these in one shot, the credentials doesnt 'chain'.
Example when I try to run

cfg, err := config.LoadDefaultConfig(ctx,
    config.WithRegion(region),
    config.WithSharedConfigProfile(profile),
    config.WithCredentialsProvider(aws.NewCredentialsCache(ec2rolecreds.New())),
)

it's trying to connect to my ec2 but what I really want to is for it to try connecting with profile first, then with ec2.

So, is there any way to achieve this like the old ChainProvider without having to add on conditions in code?
Thanks!!!
