boto3: How to delete a specific bucket policy

Question

I'm working on a bucket that has 3 policies:

'Policy': '{"Version":"2012-10-17","Statement":[{"Sid":"RestrictGetObject","Effect":"Deny","Principal":"*","Action":"s3:GetObject","Resource":"arn:aws:s3:::bucket-name/*"},{"Sid":"AddTLS1.0Restriction","Effect":"Deny","Principal":"*","Action":"*","Resource":"arn:aws:s3:::bucket-name/*","Condition":{"NumericEquals":{"s3:TlsVersion":"1.0"}}},{"Sid":"AddTLS1.1Restriction","Effect":"Deny","Principal":"*","Action":"*","Resource":"arn:aws:s3:::bucket-name/*","Condition":{"NumericEquals":{"s3:TlsVersion":"1.1"}}}]}'}

I only want to remove the "Sid":"RestrictGetObject" policy, but boto3 function delete_bucket_policy() doesn't take any arguments to specify the policy. It seems to delete all buckets.

So far, my script is like this:

def delete_bucket_policy(bucket):
    bucket_policy = {
    'Version': '2012-10-17',
    'Statement': [{
        'Sid': 'RestrictGetObject',
        'Effect': 'Deny',
        'Principal': '*',
        'Action': ['s3:GetObject'],
        'Resource': f'arn:aws:s3:::{bucket}/*'
    }]
}
    # Convert the policy from JSON dict to string
    bucket_policy = json.dumps(bucket_policy)
    try:
        response = s3client.delete_bucket_policy(Bucket=bucket)
        logger.info('Bucket: {}, Policy: {}'.format(bucket, response))
    except ClientError as e:
        logger.info('Bucket: {}, Error: {}'.format(bucket, e))

I haven't run it because i'm almost certain delete_bucket_policy() will delete ALL policies.

So, how can I delete ONLY the policy I want?
