  2. I read HCE and don't understand what is the diffrent between HCE and Card Emulation with a Secure Element?.

what are the disadvantage with the Secure Element ? i can't control on the card data/uid and on HCE I can?

This subject may be a bit old but I was asking myself the same question. Apparently the UID of the card emulated by your phone is random, but if you want to emulate the UID too you need to overwrite /etc/libnfc-nxp.conf, but it requires root privileges. At least it works (or worked) for MIFARE Classic UID.

You can see more information on this link, slides 37 and + https://smartlockpicking.com/slides/Confidence_A_2018_Practical_Guide_To_Hacking_RFID_NFC.pdf
