Any plan to support mbedTLS 3 instead of soon deprecated mbedTLS 2?

Is your feature request related to a problem? Please describe.
Hi,

We are currently using the sdk aong side mbedTLS and as you may know mbedTLS 2.X reach its end of life this year (in two weeks in fact).
cf. https://github.com/Mbed-TLS/mbedtls/releases/tag/mbedtls-2.28.9

Describe the solution you'd like
Make mbedTLS 3 usable with the sdk

Describe alternatives you've considered
Change some path to make the compilation pass.
But we've read this https://github.com/Mbed-TLS/mbedtls/blob/development/docs/3.0-migration-guide.md and there is a reason that theere is a major version bump.

For the records the (certainly first) issue is this one :
