Hi.
I have two drivers (RTX 3060 and RTX 4080Ti) and would it be possible to use them together when training RL in Isaac Sim?
Or can I only use them separately for different purposes on my single PC?
Could you be a bit more exact?
In the title you write different versions: Do you mean different hardware (you named the two GPUs) or different software?
In the text you write drivers and in parentheses your graphics cards. Drivers are a software component, a driver version could be 560.28.03 or something similar looking. They are installed into the operating system and responsible for communicating with the graphics card.
Do you just want to use both GPUs for different purposes (and drivers was a red hering) - this normally is possible as long as you can select the graphics card to use in the application - or do you want to install different driver versions for each of the GPUs? Which operating system?
Oh yeah sorry for the confusion.
I meant by two different hardwares. I would like to use 537.58 for Isaac Sim in Ubuntu 20.04 and checked that both of them are compatible with this driver.
========= Your Case ============
In this case, you seem to be lucky:

And a single container seems to support combining several GPUs.
========= General Case =========
Normally you can use both or either of them doing different tasks at the same time. Combining GPUs in a more intricate way, e.g. adding the memory of both cards or sharing the same computation task has to be specifically supported and is in most cases not very performant or even not possible. For example you can start two docker containers, each of them using one of the cards.
Containers offering Multinode Support are a good hint for combining several GPUs or several systems in the network.
