I think the best thing to do would be to send an M201 to each printer and lower the Max Accel within the printers. You could "print" a gcode snippet something like...
G28 ; Auto-Home > optional
G0 Z10 F600 ; Move up > optional
M201 X500 Y500 ; This example sets the Max X and Max Y accel to 500mm/sec²
M500 ; Save settings in the printer
G4 S2 ; Give it 2 seconds to complete the save
M84 ; Disarm the steppers > optional
The M201 might be firmware specific but there should be a command to alter the defaults in the printers. You need to check and make sure you are using the correct command.
Changing the M201 setting means that no matter the setting in Cura for Print and Travel accel (M204 with P and T or with an S parameter in the gcode) when the gcode line gets to the printer, the limit would be enforced.
Another alternative would be to put the M201 line into the startup gode of each printer. There would be no change to the defaults but once the line is read it would remain in effect throughout the print and until the printer is powered down. Upon powering it back up it would come to life with the previous default setting.
What you cannot do is fool-proof it. If someone wants to add an M201 X1000000 Y1000000 to their startup they could do it. Unless they delete the file after bashing the machine there would be a record of that.

Here comes Cura 5.9 and in this stable release we have lots of material and printer profiles for UltiMaker printers, including the newly released Sketch Sprint. Additionally, scarf seams have been introduced alongside even more print settings and improvements. Check out the rest of this article to find out the details on all of that and more
We are happy to announce the next evolution in the UltiMaker 3D printer lineup: the UltiMaker Factor 4 industrial-grade 3D printer, designed to take manufacturing to new levels of efficiency and reliability. Factor 4 is an end-to-end 3D printing solution for light industrial applications
