Disable tax on transfer order

Hi Team

We have transfer orders between two business units coming from planning and the tax is getting calculated on the transfer orders which we didn't enable. Does anyone know the configuration that is driving tax calculation and a way to disable or override tax on transfer order. 

 

We see a note stating that we can't control taxes on transfer orders and only way is to hide tax on transfer order using page composer. Hiding the tax on transfer order will not stop tax engine from calculating the tax and the Total Transfer Price will show the total of transfer price and tax. Please confirm if there is any workaround or approach that we can do to disable tax on transfer orders.
