Is it possible to force Pytorch to use less VRAM without using the -t parameter?

[curiosport]

When I tried to convert an image Pytorch threw an insufficient VRAM error, I was missing 2GB for Pytorch to accomplish the task, I was able to fix it using the "-t 512" parameter but now this presented some deficiencies in the quality of the image in which now some blocks appeared, so that's my question, is there any way to force Pytorch to use less VRAM? no matter if that takes more time the goal is to get the same quality as without using the -t parameter.

Or is my only option to upgrade to a GPU with more VRAM? I currently have 11GB of VRAM.
