Yes, you can do that by cloning the render job. To clone a render job, press the Clone button. Cloning a render job allows you to set new final render settings without the need to upload the scene again. It also allows you to clone specific animation frames within the submitted frame range. If an animation job has failed, you can use the Clone option to render only the failed frames. Note that the feature automatically pre-populates the numbers of the failed frames in the Frame range field.
In the Clone job page, you can also override the V-Ray GPU render engine for a V-Ray GPU job and force it to render with CUDA on the CPU only. Read more here.
