No. The symbol isn't queued anywhere.

DEBUG_UART_NETX is a config value that existed transiently when I wrote
the patch and I didn't clean it up properly. I suspect its visual
similarity to DEBUG_NETX_UART means it didn't jump out when I self reviewed.

Thanks for raising this. I will share a patch to remove this.
