I was wondering if it is possible to completely bypass the internal boost/buck regulator inside the DA14580, and instead supply a steady 1.41V to VDCDC and VDCDC_RF. I am trying to achieve a design that is both very space and power constrained, therefore the 80-85% efficiency of the switching regulator and the size of the 2.2uH switching inductor both make the design more difficult.

I understand this is a strange request, but an informed response from an applications engineer with more knowledge of the internal power routing in the chip would be greatly appreciated.
