Can you use your own bags at Walmart self checkout?

I'm curious to know, can shoppers utilize their personal bags during the self-checkout process at Walmart? I've noticed that some stores have specific policies regarding bringing your own bags, and I'm wondering if Walmart adheres to a similar rule. Does Walmart encourage or discourage the use of personal bags at self-checkout lanes? I'd appreciate any clarity on this matter, as it could affect my shopping experience.
