Absolutely. This is easy:
uint8_t oldSREG = SREG;
cli(); // disable interrupts
(do some stuff here)
SREG = oldSREG; // Restore register; reenables interrupts
...Make sure that when you're doing stuff, if you have a return() or something
else that takes you out of your code stream early, that you make sure you
always restore the SREG redister.
