Example hal for a xyz configuration

loadrt mux2 names=xmux,ymux,zmux
addf xmux servo-thread
addf ymux servo-thread
addf zmux servo-thread

net slowselect <= halui.mode.is-manual
net slowselect => xmux.sel => ymux.sel => zmux.sel

setp xmux.in0 [AXIS_0]MAX_ACCELERATION
setp ymux.in0 [AXIS_1]MAX_ACCELERATION
setp zmux.in0 [AXIS_2]MAX_ACCELERATION

setp xmux.in1 slow_accel_value_for_x
setp ymux.in1 slow_accel_value_for_y
setp zmux.in1 slow_accel_value_for_z

net xmux.out  ini.0.max_acceleration
net ymux.out  ini.1.max_acceleration
net zmux.out  ini.2.max_acceleration

The xhc-hb04 pendant examples include this functionality (in 2.7)

Why do you want to? My guess would be because wheel-jogging and high acceleration isn't much fun. If that its the problem then there is another possible answer:
