Under R 3.6.3 and earlier, I would link R to an alternative BLAS. Following R for Mac FAQ, Sec. 10.5, I would redirect the symbolic link $R_HOME/lib/libRblas.dylib to point to whichever BLAS I wanted to use, (either vecLib or Intel MKL) instead of the reference BLAS at libRblas.0.dylib.
With the R 4.0.0 precompiled binaries from CRAN, under $R_HOME/lib, libRblas.dylib is the reference BLAS itself, and there is no libRblas.0.dylib file. Is this by design? Is there an officially recommended alternative?
