If the hooped tunnels are empty, I would roll up the netting and secure it as you mentioned.
We don’t get a lot of snow where I am, but water pipe hoops tend to just lean and fall over. Metal hoops can bend, but you can bend them back into shape. Anything else like the bendy tent frame like hoops you can buy or attached to a wooden base is likely to snap or detach from the base.
I wouldn’t lay netting on the bare soil as it can trap unwary birds that land on it. Over crops is usually OK, but it can just encourage slugs if too low to the ground.
