The tpm_tis_spi module is by default included in all pi-kernel snaps of Ubuntu Core 20:

$ find /snap/pi-kernel/current/ -name '*tpm_tis_spi*'
/snap/pi-kernel/current/modules/5.4.0-1043-raspi/kernel/drivers/char/tpm/tpm_tis_spi.ko

To force-load it after the initrd you can add modules_load=tpm_tis_spi to your cmdline.txt in your gadget …

the module is currently not included in the initrd though, so if you would want to use it from there somehow, you would need to file an issue at:

to get it included there by default …

the list of modules included in the initrd is defined in:

in case you would also want to prepare a PR (to speed things up)
