Hola, para poder quitar esos botones es:

en la funcion 'REUSE_ALV_GRID_DISPLAY' en el parametro exporting it_excluding debes pasarle en una tabla todas las teclas de funcion que desees excluir de tu alv, como el el form abajo.

call function 'REUSE_ALV_GRID_DISPLAY'
exporting
i_callback_program = g_repid
i_structure_name = 'T_REP'
is_layout = gs_layout
it_fieldcat = gt_fieldcat[]
it_sort = gt_sort[]
it_excluding = gt_exclude[]
i_save = ' ' "Grabar Variante
is_variant = ls_vari
it_events = gt_events[]
tables
t_outtab = t_rep
exceptions
program_error = 1
others = 2.

*&---------------------------------------------------------------------*
*& Form EXCLUDE
*&---------------------------------------------------------------------*
* text
*----------------------------------------------------------------------*
form exclude.
refresh gt_exclude.
gt_exclude-fcode = '&INFO'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&GRAPH'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&VEXCEL'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&AQW'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '%SL'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&ABC'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '%PC'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&RNT_PREV'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&ALL'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&SAL'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&OL0'.
append gt_exclude. clear gt_exclude.
gt_exclude-fcode = '&OAD'.
append gt_exclude. clear gt_exclude.

endform. " EXCLUDE
