  Thomason's \'{e}tale descent theorem for Bott periodic algebraic $K$-theory
\cite{aktec} is generalized to any $MGL$ module over a regular Noetherian
scheme of finite dimension. Over arbitrary Noetherian schemes of finite
dimension, this generalizes the analog of Thomason's theorem for Weibel's
homotopy $K$-theory. This is achieved by amplifying the effects from the case
of motivic cohomology, using the slice spectral sequence in the case of the
universal example of algebraic cobordism. We also obtain integral versions of
these statements: Bousfield localization at \'etale motivic cohomology is the
universal way to impose \'etale descent for these theories. As applications, we
describe the \'etale local objects in modules over these spectra and show that
they satisfy the full six functor formalism, construct an \'etale descent
spectral sequence converging to Bott-inverted motivic Landweber exact theories,
and prove cellularity and effectivity of the \'{e}tale versions of these
motivic spectra.
