  Three-dimensional Coulomb branches have a prominent role in the study of
moduli spaces of supersymmetric gauge theories with $8$ supercharges in
$3,4,5$, and $6$ dimensions. Inspired by simply laced $3$d $\mathcal{N}=4$
supersymmetric quiver gauge theories, we consider Coulomb branches constructed
from non-simply laced quivers with edge multiplicity $k$ and no flavor nodes.
In a computation of the Coulomb branch as the space of dressed monopole
operators, a center-of-mass $U(1)$ symmetry needs to be ungauged. Typically,
for a simply laced theory, all choices of the ungauged $U(1)$ (i.e. all choices
of ungauging schemes) are equivalent and the Coulomb branch is unique. In this
note, we study various ungauging schemes and their effect on the resulting
Coulomb branch variety. It is shown that, for a non-simply laced quiver,
inequivalent ungauging schemes exist which correspond to inequivalent Coulomb
branch varieties. Ungauging on any of the long nodes of a non-simply laced
quiver yields the same Coulomb branch $\mathcal{C}$. For choices of ungauging
the $U(1)$ on a short node of rank higher than $1$, the GNO dual magnetic
lattice deforms such that it no longer corresponds to a Lie group, and
therefore, the monopole formula yields a non-valid Coulomb branch. However, if
the ungauging is performed on a short node of rank $1$, the one-dimensional
magnetic lattice is rescaled conformally along its single direction and the
corresponding Coulomb branch is an orbifold of the form
$\mathcal{C}/\mathbb{Z}_k$. Ungauging schemes of $3$d Coulomb branches provide
a particularly interesting and intuitive description of a subset of actions on
the nilpotent orbits studied by Kostant and Brylinski arXiv:math/9204227. The
ungauging scheme analysis is carried out for minimally unbalanced $C_n$, affine
$F_4$, affine $G_2$, and twisted affine $D_4^{(3)}$ quivers, respectively.
