Using 2 displays connected to an eGPU box using displayport cables, the main display is LG UK650W and the secondary one is Dell p2418d, that flickers from time to time. Is it a Dell display defective or macos's drivers? Did someone experienced this issue?

The LG is fine but the Dell flickers? Switch the DisplayPort cables and see if the Dell improves and the LG starts flickering.
