 actually I've already disabled eMMC:
In fact, I obtain:
root@arm:/# cat /sys/devices/bone_capemgr.9/slots
 0: 54:PF---
 1: 55:PF---
 2: 56:PF---
 3: 57:PF---
 4: ff:P-O-- Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G
 5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
 6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN
 7: ff:P-O-L Override Board Name,00A0,Override Manuf,BB-GPMC-001

where the only configuration loaded is the GPMC written by me. 

There is also my uEnv.txt...maybe I am missing something...

Thanks for your help.

Alberto

these changes do not seem to be makeing a difference...
