When in doubt, please check the rules
yourself. I have already asked you this repeatedly
In the past the LMP2 rules explicitely stated "only one single stage charging device and air/air and/or air/water heat exchanger" for turbo petrol engines and "two single stage supercharging systems with air/air or air/water heat exchanger are permitted" for turbo diesel engines.
In LMP1 no such limitation every applied. This means that the number and type of turbos is completely free. There are some limitation on the materials that can be used, and on the realization of variable geometry:

5.2.2 - Charging devices incorporating ceramic components apart from the bearings, variable diameter inlets and adjustable internal vanes are forbidden. Adjustable internal vanes fixed on the turbine housing are permitted for LMP1.
