“No”
Unfortunately:
Not able to use .DXF with Fritzing.
Not able to use .DXF in KiCad for other than a Graphic, such as for Silkscreen and Mask.
I Loaded the .DXF into CopperCam and generated Gcode for CNC but, without spending far too much time cleaning DXF and doing what’s needed to get usable results (which could be ‘Hit&Miss’), results were not impressive.
It might be worth your time to completely Remake the design in Fritzing - just use the PCB panel (can follow-up with the Schematic afterwards).
Then, you can copy&paste sections for smaller regions for milling…
