Keep your PVA as dry as possible. Don't leave it on the machine when not printing. Keep it with lots of dessicant in a sealed bag (I use 2 gallon zip locks and large amounts of dessicant).
Anyway according to that chart you can try "breakaway". But if breakaway works I'd consider trying PLA.
I've never tried support with TPU.
I would assume the materials will not stick at all. So you can probably use PLA as the support material but realize that the PLA probably will not ever print on top of the TPU and the TPU must be connected to itself to print on top of PLA. So for example if you are printing a table, then the PLA can easily support the main structure of the table because it can "bridge" and grip the legs. But if you are printing a model of a man with his hands pointing down to his toes - when you get to time to print the finger - the TPU on top of the PLA support it just won't stick at all and will fail. In other words you can print overhangs and bridges but not things "in thin air" supported only by support material.
Anyway I've never tried support with TPU so I could be wrong about a lot of this.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

According to this chart - it's not necessarily going to work:
