Nucleo-wl55jc - LDO / SMPS

Hello everyone,
I'm using Nucleo-wl55JC boards with the PingPong example code (which is working). I saw in the datasheet that we could have 2 different power supplies LDO and SMPS, I also saw that the SMPS mode was more economical than LDO, that's why I'd like to use it.
I'd like to know if it's possible to activate this mode in the PingPong code? Is it already active?

Best regards

KYZ.
