redirect example.com to example.com/index.html in S3 Cloudfront setup

Question

I set up s3 bucket and CloudFront setup for hosting example.com following this blog: https://simpleit.rocks/web/hostings/redirect-http-to-https-and-www-to-non-www-with-aws-s3-bucket-cloudfront-route-53-and-a-custom-domain/

Http to Https; www to non-www; all works as expected.

Now, Is there a way to redirect https://example.com/index.html to https://example.com ? Because SEO analyzer showing example.com & example.com/index.html as duplicated pages

Thanks in Advance
