  We introduce a mechanism for light-induced Floquet engineering of the Fermi
surface to dynamically tip the balance between competing instabilities in
correlated condensed matter systems in the vicinity of a van-Hove singularity.
We first calculate how the Fermi surface is deformed by an off-resonant,
high-frequency light field and then determine the impact of this deformation on
the ordering tendencies using an unbiased functional renormalization group
approach. As a testbed, we investigate Floquet engineering in cuprates driven
by light. We find that the $d$-wave superconducting ordering tendency in this
system can be strongly enhanced over the Mott insulating one. This gives rise
to extended regions of induced $d$-wave superconductivity in the effective
phase diagram in the presence of a light field.
