I downloaded the version 375.26 from the nvidia site, and just extracted
the files from the archive, without installing.

The gtk3 library in this version has a lot more symbols than the debian
installed 367.57 version:

objdump -tT ./NVIDIA-Linux-x86_64-375.26/libnvidia-gtk3.so.375.26 |grep ctk|wc -l
259

objdump -tT /usr/lib/libnvidia-gtk3.so.367.57 |grep ctk|wc -l
21


A.o., the library downloaded from nvidia has the symbol ctk_init_check
objdump -tT ./NVIDIA-Linux-x86_64-375.26/libnvidia-gtk3.so.375.26 |grep ctk_init_check
000000000002fb20 g    DF .text	000000000000000a  Base        ctk_init_check


Running the below works ok :
LD_LIBRARY_PATH=./NVIDIA-Linux-x86_64-375.26 ./NVIDIA-Linux-x86_64-375.26/nvidia-settings
