I know the Buckingham potential as what is called 'Williams' in cp2k
https://manual.cp2k.org/cp2k-2022_1-branch/CP2K_INPUT/FORCE_EVAL/MM/FORCEFIELD/NONBONDED/WILLIAMS.html

there is also a buck4ranges potential
https://manual.cp2k.org/cp2k-2022_1-branch/CP2K_INPUT/FORCE_EVAL/MM/FORCEFIELD/NONBONDED/BUCK4RANGES.html

or the genpot potential you could put together to get your desired 
interaction.
