after a while I was able to going back to that point in history to check why I was asking this
so I tried uninstaling of ststm32 and install the version you say, all is ok here, but when I try to compile anything for smt32 he answers:
PackageManager: Installing framework-mbed @ ~3.127.0
Error: Could not find a version that satisfies the requirement '~3.127.0' for your system 'linux_x86_64'
then I tried with a lower version (1.3.0 and 1.2.0), this triggers the install of mbed framework 3.126 and it works!
now I can select 16bits in the spi for the Unigraphic. Thanks!
