tpm2-tools is commonly used with the resource manager, tpm2-abrmd - But it CAN be used without, E.G. by setting the TPM2TOOLS_TCTI_NAME environment variable to communicate directly with the kernel driver: export TPM2TOOLS_TCTI_NAME=device Either directly with the TPM device (/dev/tpmN) or through the in-kernel resource manager provided by Linux kernel since 4.12 (/dev/tpmrmN) For some use cases (E.G. initramfs) it makes sense to use tpm2-tools without abrmd, so remove the tpm2-abrmd select, and instead a note in the help text that it may be needed.

TPM (Trusted Platform Module) 2.0 CLI tools based on system
|
|
API of TPM2-TSS. These tools can be used to manage keys,
|
|
perform encryption/decryption/signing/etc crypto operations,
|
|
and manage non-volatile storage through a TPM2.0 HW
|
|
implementation.

|
|
Notice: An in-kernel resource manager is provided by the
|
|
Linux kernel since 4.12. Depending on use cases and kernel
|
|
version, the user space resource manager provided by
|
|
tpm2-abrmd may be needed.
