Not that I’ve ever heard of. Because if you have to order them in terms of harm/potential harm, fiat currency ranks far beyond fractional reserve banking. There is actually support on both sides of the FRB argument, with some Austrians being fervently against it and others making the case for it (aka dichotomy between “free bankers” and “hundred-percent reservists”).
However there is virtually no one—at least of an Austrian (and even general free market) persuasion—who argues that money backed by nothing is not inherently destructive and confiscatory. Even as Milton Friedman was arguing his monetarist perspective he was constantly berating the constant printing of the Fed (and of course later in life said the central bank should be abolished entirely).
