Question about LG OLED 55ec930v

Yes, you can. I have not yet hung this TV, but the mounting points (2) are available and LG officially says that it is possible. The manual also describes how to mount it. But be careful, because of the curved shape and the only two mounting points, not all wall mountings may be suitable.

The device cannot be mounted with the standard VESA wall mounts, which is a nogo of the first order. It's a mystery to me what LG is thinking - probably nothing.
