Hello,

This was intentional given that 308 is the correct status code to use nowadays, see the documentation: https://developer.mozilla.org/en-US/docs/Web/HTTP/Status/308. 301 has some flaws like form data not going through.

but is it possible to redirect immediately to https://trodevi.com without the extra step to https://www.trodevi.com?

Unfortunately no, it's required as per web standard. You can see any popular website like Google or Facebook also do the same.
