I'm trying to avoid contact damage from magma_block's in a certain world

Describe the solution you'd like

I would like to turn off player damage by walking on magma blocks used in water elevators
If there is such a way, please advice.
If not: is it possible to implement as contact-damage or a flag?

Describe alternatives you've considered

I thought it could be done by enabling disable-contact-damage. Tried every player-damage setting. Read about every region flag but I couldn't find an appropriate way to avoid player damage done by magma blocks

Additional context

WG 7.0.3

contact damage option relies completely on the server to give that damage type to us.
apparently magma is an entirely new damage type called HOT_FLOOR. annoyingly.
