Unset Shipping Methods based on weight in woocommerce

I am using the following function to enable weight based shipping in woocommerce. For example- when the total weight in the cart is less than, 15.84, the flat_rate:5 shipping method should be activated and the other methods are getting unset.

However, I have to write all the methods getting unset individually. How to change the unset command to unset all shipping methods which are not flat_rate:5,6,8 and so on?

add_filter( 'woocommerce_package_rates', 'bbloomer_woocommerce_tiered_shipping', 10, 2 );

function bbloomer_woocommerce_tiered_shipping( $rates, $package ) {

if ( WC()->cart->cart_contents_weight < 1 ) {

if ( isset( $rates['flat_rate:5'] ) ) unset( $rates['flat_rate:6'], $rates['flat_rate:8'] );

} elseif ( WC()->cart->cart_contents_weight < 5 ) {

if ( isset( $rates['flat_rate:6'] ) ) unset( $rates['flat_rate:5'], $rates['flat_rate:8'] );

} else {

if ( isset( $rates['flat_rate:8'] ) ) unset( $rates['flat_rate:5'], $rates['flat_rate:6'] );

}

return $rates;

}
