Hi, unfortunately no, and it will probably take some time to support
snapshots for guests with UEFI.

The issue is that internal snapshots are obsolete and misses a lot of
features that external snapshots have.  They are basically usable only
for guests with only one disk, where everything including the guest
state is stored in one file.

In order to get this fixed and to get snapshots for guests with UEFI
virt-manager will have to switch to use external snapshots, there is
already a BUG for it [1].  However, it cannot be currently done because
libvirt still lacks some mandatory features for external snapshots, for
example you cannot revert to external snapshot which makes them
unusable.  There is also a BUG for libvirt to implement this [2].
