  The kagome metal KV$_3$Sb$_5$ hosts charge order, topologically nontrivial
Dirac band crossings, and a superconducting ground state with unconventional
characteristics, providing an ideal platform to investigate the interplay
between different electronic states on the kagome lattice. Here we study the
evolution of charge order and superconductivity in KV$_3$Sb$_5$ under
hydrostatic pressure using electrical resistivity measurements. With the
application of pressure, the superconducting transition temperature $T_{\rm
c}=0.9$ K under ambient pressure quickly increases to 3.1 K at $p=0.4$ GPa, as
charge order progressively weakens. Upon further increasing pressure,
signatures of charge order disappears at $p_{\rm c1}\approx0.5$ GPa and $T_{\rm
c}$ is gradually suppressed, forming a superconducting dome that terminates at
$p\approx10$ GPa. Beyond $p\approx10$ GPa, a second superconducting dome
emerges with maximum $T_{\rm c}\approx1.0$ K at $p_{\rm c2}\approx22$ GPa,
which becomes fully suppressed at $p\approx28$ GPa. The suppression of
superconductivity for the second superconducting dome is associated with the
appearance of a unique high-pressure phase , possibly a distinct charge order.
