Is there a way to suspend user interrupts for the duration of a function

If not, would it work to move the function call into a C function that

Just to clarify, if there is no functionality at the R level for evaluating
an expression without interrupts, would it be possible

You are already using BLAS in R as R includes its own BLAS library. On
Windows the 64-bit DLL is located at R_HOME\bin\x64\Rblas.dll.
If you are asking about swapping that out for an optimized BLAS, you will
