UCG28826: Can HV pin be connected to SW for DC input?

Part Number: UCG28826

Tool/software:

When supplying the device with regulated DC voltage (e.g. PFC input) can the HV pin be connected with SW pin?

I believe if X-Cap discharge is not used the HV pin may always be connected with SW pin, also for AC input applications. If that's the case then the layout can be simplified.
