STM32L476Vx LQFP100 w/ external SMPS

I was looking at the STM32L476 datasheet (https://www.st.com/resource/en/datasheet/stm32l476vg.pdf) and noticed there's no LQFP100_SMPS pin definitions (see Table 16 or chapter 7). All other packages seem to have an _SMPS section. Is this an oversight or is an external SMPS not supported on the LQFP100 package?

I noticed that the STM32L496, which seems to be pin compatible, does have an LQFP100_SMPS option, which is why I ask.

    Some packages have an SMPS version available. The LQFP100 is not one of them.

    Note that the part number between SMPS and non-SMPS parts is different, and they are not pin-pin compatible with each other.
