No, that's not a pre-requisite for daylight fill flash - it all depends on the ambient light level. Try metering the scene
WITH FLASH OFF with your preferred aperture/shutter speed/ISO combination; if the shutter speed is at or below 1/180s, then you are good to go. Just turn on the flash and use normal flash mode.
If you want or need to shoot at shutter speed faster than 1/180s, then you must use external flash + High Speed Sync mode. HSS mode would reduce your flash range significantly.
Use flash exposure compensation to achieve the fill flash amount you want. Default would give good illumination by the flash. To reduce the "flash look", you may try dialing in Flash EV -1 to -1.5.
