AffiliateWP: Disable New Referral Email for Affiliates with Store Credit Disabled

functions.php

/*-- Disable New Referral Email for PAID Affiliates -----------*/
function disable_new_refferal_email( $return, $referral ) {

	// Check to see if AffiliateWP is active.
	if ( ! function_exists( 'affiliate_wp' ) ) {
		return;
	}

    $affiliate_id = $referral->affiliate_id;
    
    $store_credit_disabled = affwp_get_affiliate_meta( $affiliate_id, 'store_credit_disabled', true );

	// If Store Credit Disable cancel email
	if( $store_credit_disabled ) {
			$return = false;
	}

	return $return;
}
add_filter( 'affwp_notify_on_new_referral', 'disable_new_refferal_email', 10, 2 );

This was very useful. I am not good with PHP but can you help me create a similar filter to not send new referral email if referral amount is less than 10. I know its a long shot, any help will be awesome.
