You can use the following request from xcb-xkb:

xcb_xkb_latch_lock_state(xcb_connection_t *c,
                         xcb_xkb_device_spec_t  deviceSpec,
                         uint8_t affectModLocks,
                         uint8_t modLocks,
                         uint8_t lockGroup,
                         uint8_t groupLock,
                         uint8_t affectModLatches,
                         uint8_t latchGroup,
                         uint16_t groupLatch);

For deviceSpec, you can pass XCB_XKB_ID_USE_CORE_KBD.
For groupLock, pass the group you want. For lockGroup, pass true.
For the other stuff, you should pass 0/false.
