Just change bootorder so that Ubuntu is listed first (you likely could
do the same from within your BIOS setup). The following is one line in
case it wraps.

efibootmgr --bootorder
0003,001E,001F,0010,0011,0012,0013,0014,0015,0016,0019,001A,001B,0001,0002,0017,0018,0000

Verify using efibootmgr -v again.
