This is prohibited under relevant regulations, parallel cables should be of the same cross section and same material.

If I may add a few more comments.Cables may otherwise be connected in parallel provided that they are of exactly the same type, run together throughout their length, have no branches and are expected to share the total circuit current in proportion to their cross-sectional . In the event of a fault, the cables should be allowed to withstand the allowable fault current without damage until the protection functions.
Hope this helps.

Welcome to the forum
Provided that the cable is not connected to the output of a VSD, it may be possible to reduce the current sufficiently by adding power factor capacitors at the end of the cable.
What is the load connected to the cable and what is the power factor??
