UCC28070: About capacitors for high frequency noise countermeasures when semi-bridgeless

Part Number: UCC28070

Hello,

How should the input capacitor (film capacitor of about 0.1 to 1.0uF) inserted for high frequency noise return in the normal circuit configuration be used in the case of a semi-bridgeless circuit configuration?
Is the X capacitor also used?
In that case, when comparing the input filter configuration between the normal specification and the semi-bridgeless specification, is it necessary to strengthen the filter in the semi-bridgeless circuit?

Best regards,
