Flannel change MTU while using wireguard + tailscale

[steache]

Hello,

First thank you for this project, it's awesome! :)

I have a question.

preface: I had problem while using flannel without wireguard while trying to use tailscale. It was pure madness (sending mysql queries, not getting responses, hanging queries :D).
But after some "research" and tinkering, I've enabled wireguard and everything started to work. (I suspect because the MTU was lowered for wireguard a bit)

Now I have question if it's possible to change flannel/wireguard-MTU because tailscale uses MTU of only 1280 and flannel/wireguard uses MTU of 1370.

Thank you in advance for any info regarding flannel/wireguard/tailscale configuration. :)
