  A complex interplay of different energy scales involving Coulomb repulsion,
spin-orbit coupling and Hund's coupling energy in two-dimensional (2D) van der
Waals (vdW) material produces novel emerging physical state. For instance,
ferromagnetism in vdW charge transfer insulator CrGeTe$_3$, that provides a
promising platform to simultaneously manipulate the magnetic and electrical
properties for potential device implementation using few layers thick
materials. Here, we show a continuous tuning of magnetic and electrical
properties of CrGeTe$_3$ single crystal using pressure. With application of
pressure, CrGeTe$_3$ transforms from a FM insulator with Curie temperature,
$T_{\rm{C}} \sim $ 66 K at ambient condition to a correlated 2D Fermi metal
with $T_{\rm{C}}$ exceeding $\sim$ 250 K. Notably, absence of an accompanying
structural distortion across the insulator-metal transition (IMT) suggests that
the pressure induced modification of electronic ground states are driven by
electronic correlation furnishing a rare example of bandwidth-controlled IMT in
a vdW material.
