As a guy in my IT department, there is little risk in this. Our company does order and provide ergonomic keyboards and mice to those who need it, and we have no rules against bringing your own. By themselves, peripherals that can't store information have no risk.
However, we do have a system in place that blocks unauthorized software downloads without IT approval, so if these peripherals come with their own software, then those downloads are blocked. Keyboards and mice typically function just fine without extra software. Perhaps it's very millennial of me, but I see no reason to not let workers have a little joy in their lives if other risk mitigation is in effect.
