I'd doubt the viability of that kind of protection on TOGG T10X.
POTUS's armored limo, the beast, is built upon a truck chassis and boasts armor 12 cms thick.
The Mercedes-Benz S-class Guard, our choice, is able to withstand 7.62 NATO rounds from all aspects. Each door of those cars weigh 250 kg's, with 70 of them just being the glass windows.
TOGG T10X in its current form can't handle these kinds of mods without significant drawbacks to its usability.
However, when our indigenous automotive sector fully matures, I expect a new brand to debut, with its niche being developing luxury cars which are able to uphold these tasks.
Like Russia's Aurus or China's Honqqi. Or Japan's... Toyota, actually.
