Can I have direct calls to LAPACK library in the generated code from MATLAB Coder avoiding the use of the LAPACKE interface?

It is sought to use the workflow mentioned in the following documentation page,
https://www.mathworks.com/help/coder/ug/generate-code-that-calls-lapack-functions.html
to have the code generated from the Embedded Coder interfaced with the LAPACK library. However, the board on which the code is to be deployed is incompatible with the generated LAPACKE C-interface.

Please note, that LAPACK is written in Fortran, namely,
https://en.wikipedia.org/wiki/LAPACK
while the Embedded Coder can generate C/C++ code. Therefore, some sort of interface should take place in order to interface the C/C++ code generated by Embedded Coder and LAPACK. Thus, it is not possible to have direct LAPACK calls in the generated C/C++ from Embedded Coder and the LAPACKE C-library is used for this reason, see the following link,
https://www.mathworks.com/help/coder/ug/lapack-calls-in-generated-code.html
Another interface is yet not supported by the corresponding workflow.
